I'm not using preempt, only IO-APIC. Each card has it's own interrupt.
The kernel is 2.4.27-pre2 with hostap and isdn-lzs-comp patch.
The dvb-drivers are the newest dvb-kernel cvs.
Today I tried a few things: After one hour the SS2 still worked, after 3h it
didn't.
Reloading the skystar2.o module is enough for it to run again.
On vdr-portal.de there are two threads [1][2] with the same problem, one
person switched the
DVB cards in the slots, another one increased the PCI latency to 128.
1h ago I tried both, let's see if it helps.
