--- Comment #8 from Colin (colin.kernel@i-pentest.info) ---
Attached is the dmesg output of 6.8.1 built manually from vanilla sources under
Ubuntu 23.10 when running `stress-ng --class cpu --seq 32`.

A few things I find odd:

- If this was a bug, surely the hardware is not esoteric enough that nobody
else would have experienced this?
- Again, it feels like this has 'gotten worse' since I first experienced it,
and older kernel seem more stable
- Building the linux kernel was segfaulting at different locations, I ended up
building it on another machine.
