I'm running Kubuntu Feisty and suspend to ram works fine (most of the
time). My problem is suspend to disk. I have an ACER Aspire 1692 with an
ATI Radeon Mobilty X600. I'm using the X11 provided drivers. Now to my
problem. As I said suspend to ram works fine and I go weeks without a
real reboot. The problem is suspend to disk. It suspends well but when
it comes back the suspend led keeps flashing, there is no sound and acpi
doesn't work properly. Also guidance takes an eternity to get the batery
status after that and to be usable. It seems to me that some part of the
system is not waking up properly but I don't know which. Also I noticed
that if I don't use the 'Lock screen after resuming' option from
guidance-power-manager, then I rarely can come back form either suspend
to ram/disk.

I attach the diff of /var/log/kern.log before and after a suspend to
disk.
