Most recent AFAICT (261f).

Do you mean this?

Sometimes (if I interpret things correctly though, this is due to an
internal watchdog in VDR triggering a restart, which now, on my system,
includes module unload/reload due to my problems).

One think fixed the problem for me, for now though:
on the kernel commandline (grub).
However the system runs stable in every other aspect, so it seems to me
that enabling apic/lapic does something which the dvb_ttpci driver
doesn't handle properly on SMP systems.
