Dear all,
this problem keeps me up for over a week now and I have to admit it is over my head.
I have Linux running on my computer for some years now. Suddently it produces Kernel Oopses in two out of three boots which make the PC unusable. They always appear in different tasks, also the "Comm"-entry is always different. Interestingly this always appears after graphical log in, never when I log in to one of the virtual consoles (ctrl+alt+F1). It is also quite funny that the system is absolutely stable once I get past the (late) booting stage.
What I have tried so far:
- Reinstalled my distribution (Debian Jessie)
- Updated the kernel from the backport repository: linux-image-3.16.0-4-amd64 --> 4.6.0-0.bpo.1-amd64
- installed packages amd64-microcode, firmware-linux, firmware-linux-free, firmware-linux-nonfree
- (also experienced a crash from a (a bit older) Mint Live USB-stick)
- Blacklisted snd_hda_intel (I thought it might have been a conflict between suond and hdmi sound)
- Performed a memtest68+, passed two times (once with, once without SMP)
I was thinking it looks like a hardware issue, because I even newly installed the system. On the other hand, as I said, when getting past the booting everything is working stable. Also it is always the same point in time, shortly after logging into the graphical user interface.
Any ideas? I am quite desperate.
Best, Gerrit
