However ums seems deprecated nowadays and we don't have direct rendering anymore: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/946677
With the default kms, during resume from suspend I'm getting:
[drm:r100_ring_test] *ERROR* radeon: ring test failed (scratch(0x15E4)=0xCAFEDEAD)
[drm:r100_cp_init] *ERROR* radeon: cp isn't working (-22).
afterwards the log and VTs are flooded with
[drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(4).
[drm:radeon_cs_ioctl] *ERROR* Failed to schedule IB !
The graphic is frozen but looks intact and the mouse pointer moves. It's possible to change to VTs.
From this state, a reboot hangs somewhere down the line shortly after the plymouth splash appears and looks normal.
Interestingly this can be rescued by pm-hibernate from the console.
After waking up from hibernate the X session continues as if nothing went wrong in between.
I tried with 3.4.0-030400-generic-pae from kernel-ppa/mainline, it doesn't flood the logs anymore but the first two errors and the frozen graphic is the same.
Attached is the syslog of a hibernate suspend hibernate cycle and lspci -vvvxxxx before, during and after.
WORKAROUND: With ums (nomodeset kernel parameter) this laptop suspends to ram just fine.
