Hi Mauro,
since you got your fingers dirty with ir, I would like to direct this
issue towards you.
One of my servers acts as a vdr with 3 video cards:

Kernel driver in use: dvb

The Technotrend ff-dvb card is used with a cam and Alphacrypt CI, that
seem to need regular driver module unloads to keep working properly.
Unfortunately, unloading all the dvb drivers is not possible, because
unloading cx8802 leads to this oops:

These code bytes are truncated; there are only 32 here. There are
supposed to be 64 of them, with the Oops-ing instruction being around
the 48th byte.
Please review your logs and provide the full Ooops.

I don't. Mauro might since he knows the code better. I just decode
Oops'es every once in a while.

Your kernel is ancient. Please try reproducing with a recent kernel from
the Kernel:HEAD repo. If it still happens, let's debug it. If it doesn't,
create a bugreport against the SUSE kernel and hope that they backport the
fix.
Best regards,
Stefan
