Summary: [KMS][RV620] Lockup on PM reclock Product: DRI Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: zajec5@gmail.com
I use today's d-r-t with my notebook.
1) Booting into init 3 and massive (50 times) switching between high and low profile No problems.
2) Booting into init 5 and switching to high profile Some kind of [black screen|lockup|reclock] loop. I get black screen for second, then corrupted and freezed display for a moment, then black screen again and so on. Sysrq works.
3) Booting into init 5, switching to dynpm, provoking short upclocking Black screen for a second, just WARNING or lockup detection (dmesgs attached)
