** Description changed:
I use Ubuntu 22.04 in VMWare Player 17.0.2 (Windows host, due to
corporate IT...). I installed the HWE kernel since I have an Intel CPU
with P/E-cores. 3D acceleration is enabled in VMWare.
With linux-image-5.19.0-41-generic it is rock solid. With linux-
image-5.19.0-42-generic it invariably crashes after anything between a
minute and an hour.
In the journalctl after rebooting it showed that X.Org had crashed
followed by a Kernel BUG/Oops due to NULL pointer dereference in
drm_gem_object_release_handle. A journalctl log from the Xorg crash up
until the kernel OOPS has been attached to this case.
This issue happened twice with this kernel. In addition, after trying to
reproduce it with kdump tools installed, I got a different issue:
refcount_t: saturated; leaking memory. in the log, leading to the OOM
killing everything on the system, including (based on what was printed
on the terminal), systemd-udevd and journald. That OOM killing never
made it into the journal however, as can be expected. I have attached
what I could get from the journal for this case as well.
One thing that helped trigger this bug (but not every time) was
launching Firefox, but once it didn't crash from that and only crashed
much much later.
Unfortunately I could not get ubuntu-bug to work for this case. I tried
"ubuntu-bug --package linux-image-5.19.0-42-generic" but it did
absolutely nothing. I'm happy to provide any additional information you
require however.
