Almost everytime I'm uploading a bigger file (65MB in this case) via. my browser (Firefox, build provided by mozilla.org as .tar.gz), my system crashes.
Issue especially happens when I'm doing different things at the same time. (Watching a video, reading email + uploading a file). System is using an SSD, bug also appears if the file is served from /tmp, though.

The issue is persistent for multiple Kernel upgrades, though. Also showed up back when Debian testing was called Stretch. Issue mostly appears on file uploads via. LTE-modem.
- Intel uCode upgrade didn't help.
- Vendor BIOS/uEFI upgrade didn't help.
- Disabling apparmor didn't help.
- Disabling/chaning IO scheduler didn't help.
- Reinstalling operating system from Debian => archlinux didn't help
- Disabling anything power saving related in BIOS, didn't help
- See Skylake crash bug arstechnica (2017)
- Basically setting c-state to 1 might also work
- A newly introduced fix resolved the problem for me. Debian Bugrepor #893393 and 4a0e3e989d66 ("cdc_ncm: Add support for moving NDP to end of NCM frame") resolved the issue. :-)
- Another similar appearing issue is showing up
Installing and setup kdump-tools (had to set /proc/cmdline => nmi_watchdog=1, otherwise kdump failed to load kdump kernel on crash).
Early bootup BIOS warning:
