After bootloader i'm getting blackscreen
monitor outputing eqvivalent of no input message
i belive that this is being triggered on initialization of amdgpu since it's happening at the point where display usually changes the resolution and adding amdgpu.si_support=0 radeon.si_support=0 in kerneli cli allows me to boot and use GUI.
This is also happening on systemrescuecd with image that worked before on this system
This issue appeared suddenly while playing witcher2 after debian sandbox update
GPU was cleaned and repasted
no visible damage on the hardware
This is Southern Islands PITCAIRN GPU (based on https://wiki.gentoo.org/wiki/AMDGPU#Feature_support) where same issue is present on radeon.si_support=1 amdgpu.si_support=0
Previously systemrescuecd was used without problems, but testing that same image now results in same issue as main OS.
Different ports on the HDMI monitor has been tried with same issue (also on systemrescuecd)
Different monitor has been tried with same result using DVI to VGA reduction (also on systemrescuecd)
Different GPU has been tested which does no have these issues
Same issue on windows
- Kernel 5.4 bug (according to AMDGPU devs)
[ 26.265638] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, signaled seq=1, emitted seq=2
[ 26.265764] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process pid 0 thread pid 0
[ 26.265771] [drm] GPU recovery disabled.
- Updating on Linux 5.5 seems to have no effect on the issue
- Based on https://gitlab.freedesktop.org/mesa/mesa/issues/1389#note_376232 parsing
amdgpu.noretry=0in kernel cli has an affect on this issue ... no effect on the issue
- Corrupted VBIOS after a system update (end-user diagnostics)
- Adapter works
- GPU doesn't seem to have any visible damage and was tested using multimeter
- Tried different monitor and port which doesn't have an effect on the result
- Works without drivers loaded

I'm also getting these green dots at the initialization of bios which were not there before.
These dots are present only there and nowhere else.
Same issue is present on using different port on different monitor (using DVI to VGA reduction)

From https://01.org/linuxgraphics/documentation/development/how-dump-video-bios i found following:
echo 1 > /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom
cat /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom > ~/rom.dump
echo 0 > /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom
which seems to be able to dump the vbios:

Assuming the time of change and visual apparence of the GPU this https://www.techpowerup.com/vgabios/117941/sapphire-hd7870-2048-120309 should be the expected VBIOS (time at the header of the ROM does not match)
Header of the file matches the time:
I was able to flash the VBIOS using atiflash.

Same issue, after reboot rom sha256sum is:

69c2b0cc0dca35b67127af47805feeee760fb453eadc67fae85a81c949fbb72d /root/afterreboot.rom
Maybe it did not flash?
Even though the header of the file is different:
EDIT: It is same as original and different from expected -> It did not flash?
EDIT: Tried different ROM -> It flashes using atiflash on linux
