Hi,
I'm getting an IRQ lockup on a Pinncale PCTV Sat after some time when watching
TV. On my old system (Asus A7V KT133A, AMD Thunderbird 1.4 GHz) the card
worked nearly flawlessly but in my new system (Asus A8V-E, AMD64 3000+) I'm
getting this IRQ lockup usually after some minutes/seconds after starting the
stream.
I tried setting the allowed loop count in the bt878 interrupt service routine
to 1000 and more, but this just made my system quite irresponsive.
Just closing the player and tuner and restarting them does not make the stream
run again.
When I rmmod bt878, dvb_bt8xx and cx24110 and reload them again I am able to
get a stream out of /dev/dvb/adapter0/dvr0 after tuning.
Has someone got an idea how to solve this problem? Should I adjust PCI latency
somehow?
Instead of just clearing the int_mask in the interrupt service routine in
bt878.c one could try to reinit the card (just like removing the module and
reinserting it). Any suggestions how to do that?
Best regards,
Adam
