Public bug reported:
My PC keeps randomly crashing with no apparent reasons. Everything works
fine one moment, the next it starts rebooting itself. I tried to
diagnose it with journalctl/dmesg logs, and it seems the crashes related
to a bug in Intel i915 driver (however, I am not sure). I've changed
boot load parameters to i915.enable_fbc=0 i915.enable_hdcp=0
i915.enable_psr=0 crashkernel=128M, but it did not seem to have any
effect on the crash pattern.
PC configuration:
Intel i5-9600k, MSI Z390 Gaming Edge AC WiFi Motherboard with the latest BIOS
(7B17vAD), 32Gb RAM, 2NVMe drives (one used as Linux, another as data storage)
+ 1 HDE, 2 monitors, both on Intel integrated graphics controller (HDMI+Display
Port).
