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.</pre>
