Yeah, i disabled power saving mode. So my display never goes to sleep anymore. That solved it i know i am killing the MacBook . But the previously the MacBook was loosing my work with every panic.

So yep disabled the monitor from turning off. I should say my setup is a 100% on an external monitor. Only times I open the lid is when things doesn't boot up

And this error speaks of a Thunderbolt power failure. When I look under Thunderbolt devices I don't see any device listed there either.

Alright! Thanks for your reply.
That solution won't work for me as my ports died at the same time and the computer won't charge😅

do you mean your MacBook had a panic once and then everything gone kaput? can't boot up anymore? did you try the recovery modes? CMD+R CMD+S etc? also, clearing out the SMC?

Alright! Thanks for your reply.

Yeah, tried that. SMC reset doesn't help I've also had the logic board replaced twice but the problem keeps returning. Computer is still on warranty, so the repairs are free but annoying.

I jinxed myself, It crashed itself during a shutdown to install the latest Catalina Developer Updates. But didn't have to unplug anything. it rebooted back in the usual fashion. However, I have reduced the number of USB Hubs from 4 or 5 to 2. both connect via USB-C provides 3 USB3.0 interfaces. I switched the HDMI to a newer adapter which I have been using at work without any issue. If things are stable with the new adapter I will try turning sleep on again.

This 4 USB-c ports is really not enough. My standard setup
2 x WD Passport 2TB drives
1 x TASCAM - Audio Interface
1 x USB PNP Mic
1 x USB Apple Keyboard
1 x Power USB-C

And I have to plug these guys in as I do some projects
Iphone,
GoPro,
magic touch pad for charging,

do you have any recommendations?

Mine is in for a repair right now, replacing logic board and top case. Hope that fixes it this time and that the issue doesn't reappear.

@arneson Do you have VirtualBox or Parallels installed? I somehow convinced myself that this is the reason for the crashes. What did you tell them when you brought it to the apple store, since I'm assuming this issue isn't reproducible?

Latest panic, (unplugged USB-C power connector, plugged USB power connector USB-C adapter, Plug USB-C Ethernet port to USB-C port in MacBook.

on crash and reboot, the external USB keyboard was not recognized. had to open the lid type password. This busts the hypothesis that disabling power savings mode fixes the issue.

Worth mentioning had just booted a VMware image of ubuntu assigning 8 cores (50% of cores) and 8GB (25% RAM) moments before this happened.

there is no https://opensource.apple.com/source/IOPCIFamily/IOPCIFamily-370.100.21 in apple source code. will take a look at the source code that ls closest match to get a bit of a pinpoint to the actual crash

#Catelina 10.15.4 Beta 4

this is the function that this 32 bit code is leading me to, but given that I am running Catelina i doubt this is the correct file, or even if its remotely close to Catelina. I will try to see if my developer licenses allow me to get access to the actual code running

Every since I unchecked the Enable Powernap setting, I haven't suffered a crash. Only time will tell. I'm really upset about this.

here is a summary of what I am able to gather so far

IOPCIBridge
is responsible for configuring and bridging (i am guessing some sort of mmap) PCI devices (that's the part of the code that crash with power state issue). it has a function called systemPowerChange

so the problem is definitely in the new IOKit Framework and how it manages the IO Registry. And most likely on hardware that is not written or tested against Apple's evolving spec on IOKit. My hunch is the crash is due to bad firmware on an untested device.

Potential Isolation approach to the problem

eliminate all none Apple nor None Apple Store promoted USB-C devices out of my system.
If this approach proves to work as expected without panics then the culprit is some misbehaving vendor firmware code. 

TLDR ;

Documentation lacks details on what exactly the function supposed to be doing.

It is also worth mentioning that this part of the kernel code IOKit to be exact is also flagged as Beta, so it's possible that there are lot of bugs, and this panic is just one of many variants.

If you like to know more about this approach of IO Registration and Bridging there is a tool from Apple called ioreg

IOREG

what is IO Reg, IO Registery, What does it have to do with IOPCIBridge

without any arguments, it will dump the state of the current IO Registry.

Light at the end of the tunnel (Maybe?)

It looks like hacking ioreg can potentially provide a lead to miss-behaving hardware that doesn't play nice with Apple's IOKit.

Implementation of such a state tracking system does have it's own challenges of being able to have produced a near most state prior to panic and having it persisted without much IO weight on the actual machine. I believe those problems can be solved with another machine and UDP packets.

First step towards the goal

I found the ioreg source from Apple, and manage to create a project that can compile and produce a usable output just like the binary version they distribute.

matter of time and luck

So from now on, it will be a matter of time, luck and time If I am able to produce something. I will keep you guys posted here. I can write C code but i have never written Objective-C so challenge accepted.

before you go

i recommend at least getting ioreg

and running it to see the size of your IO Registery and the depth of it. It will give you some idea of the complexity of this panic and how it maybe difficult to reproduce.

I got this problem recently, and one of the type-c port is dead. Genius Bar suggest me to replace the logic board.
After reading you guys talking, I doubt if replacing the logic board will solve the problem.

After 3 logic board replacements I decided to stay on 10.15.1 and everything has been fine since. So I’m fairly convinced its a software issue on 10.15.2+

I bring my macbook Pro to Genius Bar, hoping to downgrade to 10.15.3 or less, but I was been told that there is no way to downgrade to the lower macOS since the new T2 chip ( or the macbook Pro 2019, which is mine)

Yeah, but since they replaced my logicboard(with t2 attached) I got a clean install of what it was delivered with (10.15.1)

They did however tell me you can’t ever go lower than what it came with.

@arneson - my machine is being repaired right now. My problems became worse since I last updated this thread. My ports also stopped working permanently after the kernel panic and the only thing I could do is forcefully reboot the machine via the power button.

I have collected many kernel panic logs over this time period (January 2020-May 2020) and I even have a video evidence.

Unfortunately, the issue only appears to happen after about 6-8 hours of use. I don't know how to reproduce the issue.

@rmccullagh
Since my third repair I’ve left the machine in 10.15.1 and it has been fine ever since.

I let it go to sleep etc, no special settings and it just works as expected. Terrified to upgrade osx though so thinking I’ll probably stay on 10.15.1 until 10.16.X is released and hope they fixed it by then.

Just hope I don’t need a newer Xcode-version before that, since that update is blocked for me until I upgrade.

@rmccullagh I have the same kernel panic issue thunderbolt3 poweron failed with IOPCIBridge.cpp:1398.

I'm able to reproduce it by plugging in the Apple USB-C to USB-A/HDMI/Power Passthru dongle (without anything plugged into the dongle) into a port on the right side of my 16" MBP. After plugging in, my machine crashes consistently within 2 minutes. The ports on the left side of my 16" MBP don't recognize the dongle. If I connect a USB-A keyboard to the dongle on the right side, I'm able to use it for a minute before my machine crashes.

All power-saving features are disabled. I also crash when waking from sleep (without anything plugged in).

@devzer01 @arneson I wonder whether we can "patch" this issue by downgrading to /System/Library/Extensions/IOPCIFamily.kext to the version found in 10.15.1. @arneson what do you get with the following command:

kextstat -b com.apple.iokit.IOPCIFamily  # on 10.15.4 outputs:

@devzer01 just wonder if you got anywhere with your laptop? I'm having the same issue on a 15" 2018 MBP, out of warranty now and Apple guys told me it would be like $800 to replace the board if that's the issue, they couldn't figure it when I took it in for diagnoses. really sucks.

Edit: just saw this: https://apple.stackexchange.com/a/392859
going to try disabling the Thunderbolt Bridge to see if that helps

Hey guys, update from me.

After staying on 10.15.1 for ages, I decided to do something about it.

I managed to update through to 10.15.6 and the computer is stable. The fix for me was to apply the “Combo updates” for each version instead of the actual update through software update.

https://discussions.apple.com/thread/7565291

Doing that seems to have fixed my issues and my computer has been running stable for a month or two now.

Attempted to upgrade to Big Sur Beta, it didn't solve the issue (Error now is in a different line of IOPCIBridge.cpp, so I assume it was updated but issue wasn't solved)

edit:
I stand corrected, it seems to have mitigated the issue, I'm experiencing less resets

@aviadsteps good to know, I've been debating if I wanted to upgrade, with the thunderbolt bridge disabled my system seems much more stable, I also don't let it auto-sleep, I manually put it to sleep.

Hey, I have 2018 MBP and started facing this issue a lot after 11.4 update. Then came the 11.5 update and issue seemed mitigated however, I face the issue every time I fire up my machine in the morning.

I tried shutting down my machine overnight and next morning did not face the issue. But if it auto-sleeps, I face the issue again.

Disabling thunderbolt did not make a difference for me. Any update on this issue by anyone?

Catalina 10.15.7 here - this happens when my computer sleeps.
