Public bug reported:
Hi!
I'm reporting a problem that is similar but not identical to bugs #13957
and #12483. These bugs are about hard freeze after removing the power
plug. I experience hard freezes approximately 5 minutes after plugging
it IN on a running system or booting a system with power plug in.
Occasionally it happens one more time after a reboot (never more than 2
times).
When the system is about to hang up hard disk is active for a while
(looks like it's flushing cache) and when it's done system hangs up with
CapsLock LED blinking.
It started to happen after upgrade from Feisty to Gutsy.
My hardware is Fujitsu-Siemens AmiloPro V3505 laptop running
2.6.22-14-generic SMP kernel.
