Priority: medium Bug ID: 66940 Assignee: dri-devel@lists.freedesktop.org Summary: Mobility Radeon HD 5650 doesn't resume from suspend on kernel 3.11 (linus and drm_next) Severity: normal Classification: Unclassified OS: All Reporter: mail@3v1n0.net Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
Created attachment 82459 --> https://bugs.freedesktop.org/attachment.cgi?id=82459&action=edit dmesg
I've tried running linux 3.11 from both linus and drm_next branches, but when using the radeon drivers it's impossible to resume from suspension.
It's quite sure that the problem is in radeon module, because unloading it (and switching to my intel card with vgaswitcheroo) works fine. Also, enabling the pm_trace sys-node it highlights that the radeon device caused the freeze:
from dmesg: [ 1.286810] Magic number: 0:660:725 [ 1.286815] hash matches /home/marco/Dev/debs/linux/drivers/base/power/main.c:575 [ 1.286829] block loop5: hash matches [ 1.286867] pci 0000:01:00.0: hash matches
^ This is the PCI id of my radeon card
cat /sys/power/pm_trace_dev_match: block radeon
This is a regression, since linux 3.10 works well.
