--- Comment #1 from Rafael J. Wysocki rjw@sisk.pl 2011-05-03 20:45:22 --- Strictly speaking, this is not a regression, because the radeon driver with KMS has never worked correctly for you in this respect, right?
Now, while the ultimate fix would be to rework device drivers so that they don't allocate memory from their ->suspend() callbacks, it's not quite realistic to expect that that's going to happen any time soon.
For this reason, I'll try to provide a workaround for you.
