Hi Ronald,
Hmm.... after modprobing zr36067 /proc/interrupts says:
[root@localhost root]# cat /proc/interrupts
CPU0 CPU1
0: 42250 42731 IO-APIC-edge timer
1: 1 2 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 0 1 IO-APIC-edge rtc
10: 30 31 IO-APIC-level LML33[0]
11: 899 918 IO-APIC-level via82cxxx, eth0
12: 0 0 IO-APIC-edge PS/2 Mouse
14: 1373 1390 IO-APIC-edge ide0
NMI: 0 0
LOC: 84899 84898
ERR: 0
MIS: 0
So it looks like it's unshared on IRQ10, which is consistent with the
drivers understanding of itself:
Feb 11 10:11:31 localhost kernel: MJPEG[0]: Zoran ZR36067 (rev 2) irq: 10,
memory: 0xdb020000
If I fire up xawtv for a while the interrupt count does increment as
expected. But considering this is a dual processor machine, I wonder if this
is an SMP bug of some sort. I'll try compiling a uniprocessor kernel and
pulling one of the processors out. In the meantime, heres the boot log to
ponder:

no, that's something having to do with not being able to handle

Hmkay... Does the card have its own IRQ?
