Public bug reported:
Hi,
there is a bug in Linux kernel. Problem is with graphic card.
I see these lines in dmesg:
[ 1269.113618] i915 0000:00:02.0: GPU HANG: ecode 9:1:0x87f99eb9, in blender
[7901], hang on rcs0
[ 1269.114626] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0
And graphical software are very unstable. They're crashing. It looks
like, that graphical software is unstable, but problem is in the kernel.
For example - using Blender is totaly unstable.
I was looking for a solution. I found some discussion and there was
written, kernel >5.5 is solution. So I tried kernel 5.7.7 and bug still
persist. Kernel 5.7.7 was installed from Ubuntu repository. Log from
kernel 5.7.7 is attached.
Modeling in Blender for an 30 minutes is the best way, how to
repruduce this bug.
