Or ACPI, or SMP PREEMPT.

Same results you've mentioned before.

So, if you are getting relieble crashes, please try

* to get minimal test-case,
* kernel targeted for experimental/sid:
  deb http://kernel-archive.buildserver.net/debian-kernel trunk main
* or latest upsteam one.

And please collect and send all fault logs. This can be useful, when
tracing problems.

There's one similar report in lkml, i've found:

  Archived-At: <http://permalink.gmane.org/gmane.linux.kernel/474449>
  Message-ID: <1165685215.4563.6.camel@localhost>

But it have no follow-ups. Thus, as more info you can collect, more
chance we can get upsteam interested.
