I am on FreeBSD 14.2-RELEASE on my desktop PC with AMD 4750G Renoir GPU.

% freebsd -ku

drm-kmod and gpu-firmware are compiled from ports.
All pkgs and system are up to the date.
System will freeze for seconds, later for minutes - mouse cursor will move but
won't do anything, audio will play but video will stop, it would not be
possible to switch alt-tab programs or do anything on the PC.
There is nothing related in /var/log/messages.
As the uptime grows, freezes will be longer and longer (5 minutes and longer is
not unusual, measured personal record is 27 minutes), VM will stop working,
audio too, keyboard and mouse won't react.
Sometimes problem occurs freshly after restart, sometimes days are needed for
reproduction.
Same thing if picom is used or not.

Everything was working without problems for the past 5 years until few weeks
ago. I think it started on 14.1, before 14.2-RELEASE upgrade, but I am not sure
anymore (although I remember that I did upgraded all pkgs and rebooted after
few months of uptime and then problem started).
Nothing has changed HW wise in years. RAM is healthy (according to memtest),
ZFS doesn't report problems on NVMe nor SATA drives.

I did try to use drm-515 but that ends with kernel panic.
Rebuilding older drm-kmods from ports didn't help.

My problem seems similar to the
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=284480 but there are no zpool
scrubs involved.

Is there something I can do? This is making my system unusable (and having
freezes of 5+ minutes every windows switch is not nice either)
