Bug Description
Gutsy was 100% OK with hibernation on this laptop.
In March, Hardy was actually still hibernating on my laptop, but it was freezing with "drm_sysfs_suspend" on the screen, so I had to manually press the On/Off button for 5 seconds once the disk activity stops.
This was as per Ubuntu Bugs #197064 and #201086.
Since I installed Hardy RC, hibernation failed completely (system freezing and nothing saved on disk) with several messages of this kind on the screen:
"BUG: soft lockup - CPU#0 stuck for 11 s! [ipolldevd:5623]"
A few days ago, after a kernel update, it started to fail with a different message as the last screen line:
"Suspending console(s)"
Right now, with an updated system, nothing changed, which means 8.04 is a severe regression over 7.10 with regards to hibernation!

This is valid for all the kernels! I have tried here the RT one just in case.
