Package: linux-image-2.6.26-1-686
Version: 2.6.26-3
Followup-For: Bug #494036
Since kernel 2.6.25 I've got several kernel freezes without any reason
or log entry.
It seems to be related to some BIOS/rtc/HPET issue.
With any kernel 2.6.24 everything was fine.
Because there is nothing in the logs in time of freeze it is hard to
give more information.
After I use the Ingo Molnar's netconsole I got on a other computer the
log message
rtc: lost 787 interrupts before freezing.
The workaround hpet=disable works mostly.
In the ChangeLog-2.6.27-rc5 is a possible fix:

rtc: fix deadlock
if get_rtc_time() is _ever_ called with IRQs off, we deadlock badly
in it, waiting for jiffies to increment.
So make the code more robust by doing an explicit mdelay(20).
This solves a very hard to reproduce/debug hard lockup reported
by Mikael Pettersson.

So I'll try kernel 2.6.27 next time.
