Dear Maintainer,
Since upgrading from kernel 6.12.27 to 6.12.29, my system occasionally
hangs (evidenced by the mouse pointer freezing in place) for roughly
0.3 - 2 seconds at a time.
These hangs are accompanied by the following line in dmesg, often
repeated several times:
amdgpu 0000:03:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data
I believe this upstream report is the problem I am experiencing:
https://gitlab.freedesktop.org/drm/amd/-/issues/4238
The problem vanishes when I use a custom build of kernel 6.12.29 with
commit ID 468034a06a6e8043c5b50f9cd0cac730a6e497b5 reverted. Upstream
commit ID: f1c6be3999d2be2673a51a9be0caf9348e254e52
