Are there really issues concerning SMP in dvb-kernel?

I've been using dvb-kernel since over a year now on a Pentium 4 HT 
processor (don't know whether it is compareable to a real SMP system) 
and the only issue I had so far was with the SkyStar2 driver which had a 
not SMP save IRQ handler. But the problem was solved soon after I've 
reported it.

I'm using SuSE 9.1 with a selfcompiled kernel 2.6.9 (current dvb-kernel 
drivers are (un)loaded in runvdr). In /usr/src/linux/.config I have

CONFIG_SMP=y
CONFIG_NR_CPUS=2
CONFIG_SCHED_SMT=y
CONFIG_PREEMPT=y

Bye.
