The only thing in the cx23885 driver that tries to schedule work, and thus the only thing that could possibly pass in a bad argument, is the netup_ci_slot_status() function. It gets called when an IRQ comes in indicating a GPIO[01] event, and the driver thinks the card is a NetUp Dual DVB-S2 CI card. That's consistent with the "fatal exception in interrupt", but without the backtrace, one can't be completely sure this call to queue work was initiated by the cx23885 driver and a problem with cx23885 data structures. (But it is the most likely scenario, IMO) I just can't see how netup_ci_slot_status() get's called for your card. > Any way to get the dump to go out the serial port? Does 9600 baud help?
