Problem Description: System freezes while resuming from suspend-to-disk;
nothing in logs, nothing on the vga console

Steps to reproduce: Start the system, work for a minute or two (what I did was
to run X, run browser and exit), suspend (no problem here), resume (freezes after 
"Stopping tasks: =============..." appears on the screen again).

Actually I was able to sucessfully resume with 2.6.14-rc5, but only once
(start->login->sync, sync->hibernate)
