First time module loaded and zapped some channel. At this point there is no errors. /proc/interrupts shows some irq's for cx23885. Then rmmod-insmod and szap again. Voilla! No irq vector. /proc/interrupts shows zero irq calls for cx23885. In my case Do_irq complains about irq 153, dmesq says cx23885 uses 45. My first look not catch anything in lspci. For now I'm using workaround - find register and bit in cx23885 to write to disable MSI registers. In conjunction with particular card, naturally. Regards Igor
