I've got a Dell Latitude D630 that does this in "lenny", I suspect
it's a kernel bug, since the hardware was stable under "etch".
I got some relief by using "clocksource=acpi_pm noapic" as kernel
arguments at boot-time, but it's done it one time since then --
sounds like you tried something similar.
I can't find the bug-report thread I was looking at just now,
but if you google the error messages, you can find a bit of
mailing-list traffic (mostly Ubuntu), and some discussion
of work-arounds, mostly involving kernel arguments.
Sorry this isn't more helpful...
