Subject: [2.6.23] IBM X41 looses time after Suspend2Disk

Hello Thomas, Pavel, Rafael!

I have an IBM X41 tablet pc running 2.6.23 with the following problem:
Suspend2Ram work fine, but when I do a Suspend2Disk (echo disk >
/sys/power/state), the notebook hangs showing the following lines:
        Stopping tasks ... done.
        Shrinking memory... done (49361 pages freed)
        Freed 197444 kbytes in 0.64 seconds (308.50 MB/s)
        Suspending console(s)

When I repeatedly press some keys or move the TrackPoint, the SwSusp
continues and the notebook powers off.
On reboot, the notebook resumes but hangs showing the following screen:
        Stopping tasks ... done.
        Loading image data pages (62483 pages) ... done
        Read 249932 kbytes in 18.63 seconds (13.41 MB/s)
        Suspending console(s)

Generating interrupts by pressing keys or moving the TrackPoints makes
the resume continue. But after that, the notebook looses time, xterms
don't get updated until I press a key, the beeper beeps until I press a
key, etc.

Any idea what the problem might be?
