No, and I've even plenty physical RAM free (my machine has 4 GB
memory and I use less than 2 GB), and htop says about 76 over
9695 MB swap used.

No, the only dmesg messages I get after the boot are
dell_wmi: Received unknown WMI event (0x11)
and according to /var/log/kern.log, then don't occur at the same time.

OK, I'm going to try that (I have 2.6.39-1, 2.6.39-2 and 3.0.0-1 also
When the problem occurs, the mouse can still move and I can switch
the desktop with the window manager (fvwm). But applications like
xterm and iceweasel are frozen (e.g. typing in xterm has no effect
until the disk is no longer accessed).
