Package: linux-image-amd64
Version: 4.19+105
Severity: important

Hi.

Im currently running debian buster kernel and i experienced some segfaults.
Segfaults are random, which prevents me from pinpointing the trigger.
First i tried disabling overcommit on memory, the behavior stoped.
Today it started during installing updates for libreoffice. Two first
segfaults were caused by xfdesktop, the two more with gmain.
Another odd thing is that the error is in libglib and the code is completly
identical. The RAM was tested with memtest86+, memtester. Previous release
with backport kernel was working perfectly even with overcommit. I
guess there is a small chance of defective hw.
My next suspect is apparmor. Im going to use the system with disabled
apparmor to see if this problem persist.

Thank you

I hope this helps make debian more stable and reliable.

Have a nice day
