<pre>Status update: After updating to 3.18.1 vanilla and booting with radeon.dpm=0,
suspend/resume now works reliably.
Hibernating/resuming still fails, but only and always on the second cycle, the
first cycle seems to work fine now:
1) Boot with radeon.dpm=0 (radeon.dpm=1 seems to have its own stability
troubles)
2) hibernate
3) resume
4) hibernate
5) resume => kernel panic after loading pages (counting from 0% to 100%).
It seems the kernel panics when trying to switch back to the X screen.
Unfortunately, I am for some reason no longer able to boot with a 3.6/3.7
kernel (maybe because of an udev problem), so I cannot bisect - and I am not
sure any 3.6 kernels worked reliably before because I remember it had issues
too.
I've tried to suspend/resume between the hibernation cycles, but that does not
change anything; hibernate/resume will still fail on the second resume attempt.</pre>
