Summary: RV620 locks up on starting/quiting 3D app
Product: Mesa
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/Radeon
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: zaj...@gmail.com
I use Mesa master git and agd5f's r6xx-r7xx-3d git.
IIRC I didn't experience any lock up while running 3D app. However it happens
often while starting (first frame) or quiting.
It's hard to reproduce with glxgears (last 20 tries of start&quit didn't hit
bug) but really easy to reproduce with morph3d. Starting&quiting morph3d about
3-5 times is usually enought to lock up.
When machine locks up I can ssh to it or use SysRq.
dmesg | tail doesn't show anything drm related, but I didn't use debug param
when modprobing drm. When I try debug=15 every lock up is hard one and I can
not ssh to machine nor SysRq anymore.
Based on 3 cases, last line of /var/log/Xorg.0.log seems to be:
exaCopyDirty: Pending damage region empty!
One idea I've got on IRC was:
<suokko> zajec: Sounds like possible gpu hang so best info would be what did
the latest cmdbuf include
but don't know how to get that cmdbuf.
