Dmitri,
This problem may be related to the firmware loading race described here:
https://bugzilla.kernel.org/show_bug.cgi?id=15294
I still have not fixed that bug yet.
But for your problem, perhaps you can try:
echo 120 > /sys/class/firmware/timeout
as root in the initialization scripts to lengthen the firmware loading
timeout to 120 seconds. Maybe that will work around the crash.
I'll try and look at what is going on in your crash dumps, if I have
time.
Regards,
Andy

Keep forgetting, reply on this list doesn't go to the list unless you
reply all or manually change the address:(
Could this problem also be related to the tuner problem I've been having
with one tuner stop tuning? Because it is on a Athlon64 x2 (dual core).
I put up logs with debug on. First set was I think about 24hrs with no
crash, then the file ext new and new2 where each copied out after the
tuner was found crashed.
