I was wondering, if someone tried 2.6.36-rc kernels with PCIe MSI enabled. With TeVii s470 after rmmod cx23885 && insmod cx23885 then szap some channel I have 'No irq handler for vector' message. After reboot it's OK. I think it's A/V core interrupts involved. igor@useri:~$ szap -l10750 bridge-tv -p reading channels from file '/home/igor/.szap/channels.conf' zapping to 5 'bridge-tv': sat 1, frequency = 12303 MHz H, symbolrate 27500000, vpid = 0x0134, apid = 0x0100 sid = 0x003b using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' Message from syslogd@localhost at Tue Aug 31 00:55:32 2010 ... localhost kernel: do_IRQ: 1.137 No irq handler for vector (irq -1) Message from syslogd@localhost at Tue Aug 31 00:55:33 2010 ... localhost kernel: do_IRQ: 0.137 No irq handler for vector (irq -1) Message from syslogd@localhost at Tue Aug 31 00:55:34 2010 ... localhost kernel: do_IRQ: 1.137 No irq handler for vector (irq -1) Message from syslogd@localhost at Tue Aug 31 00:55:35 2010 ... localhost kernel: do_IRQ: 0.137 No irq handler for vector (irq -1) It is similar issue with NetUP DVB-S2 , but CI involved through GPIO interrupts. Compro e650f works well, though it uses neither A/V core interrupts nor GPIO interrupts. -- Igor M.
