In the spirit of festive testing I would like to say that the oops that I enjoyed throughout rc2-bk* is still present in -rc3. -mm series does not have this problem.
I boot -rc3 single user then do modprobe -r dvb-bt8xx The system oopses, but I can do a clean reboot (original -rc2 could not umount cleanly).
