 Posted: Sun Oct 23, 2022 7:08 am Post subject: Kernel faults - on my Gentoo Linux |
 |
|
I seem to be seeing this for a while now, and wonder if anyone else has been seeing this?
I primarily notice if I try play videos in Chromium and Firefox at the same time although this is not the only time.
I suspect it's something going wonky between the kernel and the nVidia proprietary driver, in particular, since I replaced my nVidia video card with a Gigabyte GeForce RTX 3060

I show Thunderbird because it also uses libxul and the kernel log version does not specify which is causing the problem.
Any suggestions?

At first glance I'd say the kernel is not playing any role in what is happening. Basically you have some Web processes (some tab content) that is crashing (Segfault) and the kernel is just reporting that.
Why is it crashing...I have no idea, sorry. libxul is internal to Mozilla Firefox, therefore I'd say that it's firefox alone that is not liking something and crashing.
Sorry for not being more precise. |

lyallp,
Segfaults are memory access errors trapped by the kernel.
The faulting process tries to access memory that its not permitted to. The kernel kills it and leaves a note in dmesg.
It can be caused by a built time error or a run time error.
Boot into memtest86 and run a few cycles. That way it can test all of RAM and report the real location of any errors.
When you run it under the kernel, it can't test the RAM occupied by the kernel and errors are reported within the virtual memory space allocated by the kernel.
Its non trivial to derive physical RAM addresses from them.
If you use overclocking, including XMP, turn it off. XMP is overclocking by another name.

I tried doing memtest, no problems there.
I would hope that a core file was generated, but there are none.
I don't overclock, I run everything at standard speeds.
It's not a huge issue, the errors occur and generally I don't notice them at a user level, but I do monitor my system logs and would prefer not to see them.
