Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

I was using the computer as normal, checking a boring website in
Chromium browser while Firefox was also open.  Out of the blue, there
was a hard freeze, the mouse pointer was frozen and I had to long
press the power button to restart.  The previous kernel versions had
been quite stable.  I had also noticed that the graphics were
glitching for a bit, like the mouse pointer would glitch. I used to
have this behavior often like 6-12 months ago.  First it would get
glitchy, then it would crash.

Control: tags -1 + moreinfo

Is this issue still reproducible for you with 6.12.57-1 in trixie (and
if yes, can you please as well verify with the kernel in unstable, as
of writing 6.17.8-1?).

Salvatore
