I'm getting this badness in redraw_screen when my iBook wakes up with
2.6.0-ben3:

Badness in redraw_screen at drivers/char/vt.c:596
Call trace:
 [c000bd50] dump_stack+0x18/0x28

 [c0007d0c] ret_from_syscall+0x0/0x4c

(The three unnamed frames are inside pmac_wakeup_devices,
powerbook_sleep_Core99 and pmu_ioctl).  Does pm_restore_console need
to acquire the console lock, or is that the duty of the callers?

Andreas.
