Using mainline kernel up to commit 03cd3739818d3fa7f973d0fb6d3aa63122ea00a0 Merge: 1067b6c 06b4367 Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Thu Jun 3 07:20:28 2010 -0700 Merge git://git.kernel.org/pub/scm/linux/kernel/git/sfrench/cifs-2.6 i got hard-freeze right after monitor goes into standby mode (blinking led on monitor itself). Same kernel goes into standby mode OK with nouveau driver or with modprobe radeon modeset=0. This was observed right after console login, but starting X before makes no difference.

Is this a recent regression? Has s/r worked previously for you with kms?
