Public bug reported:
Hibernate is very flaky in Feisty on my CL56.
When I hibernated my computer (very few apps running), it failed to
hibernate. Instead, I got the screen lock window back. However, the
keyboard was completely dead to X. ctrl-alt-bs, ctrl-alt-f1 etc. all
had no effect. The mouse pointer moved as expected, however.
I tried sleeping the computer (this sometimes helps the extremely flaky
gnome-screensaver), but it also failed to sleep.
I ended up having to sysrq-reboot the machine (it still responded to
clt-sysrq-b)
This machine was pretty much 100% stable at hibernating in Edgy.
The log indicates a possible dbus failure?
