Priority: medium Bug ID: 66425 Assignee: dri-devel at lists.freedesktop.org Summary: "failed testing IB on ring 5" when suspending to disk Severity: normal Classification: Unclassified OS: Linux (All) Reporter: austin.lund at gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: DRI CVS Component: DRM/Radeon Product: DRI Created attachment 81770 --> https://bugs.freedesktop.org/attachment.cgi?id=81770&action=edit Full log from suspend test With kernel 3.10 suspend to disk seems to case a problem with my GPU. I did this to test suspend: echo devices > /sys/power/pm_test echo disk > /sys/power/state It takes quite a while to return to the console and the system becomes unstable. Strangely suspend to ram doesn't seem to have any problems. The relevant log lines seem to be: PM: Allocated 2886788 kbytes in 0.39 seconds (7402.02 MB/s) Freezing remaining freezable tasks ...
