NI6036 PCMCIA Card Continuous Acquisition Stops from Blacker, Phil M on 2004-11-30 (gmane.linux.comedi)

I have installed comedi-0.6.69 and comedilib-0.7.22.  I wrote a program to
continuously acquire data using a PCMCIA NI6036E card, but it would randomly
freeze.  There would be no error returned by comedilib or in the syslogs.
The card will just stop returning any samples.

I enabled DEBUG_INTERRUPT, DEBUG_STATUS_A and DEBUG_STATUS_B in
ni_mio_common.c.  With this the final messages before the card stops are:

ni_mio_common: interrupt: a_statusa033 m0_status=00000000
A status: interrupt_a fifo_half_full start stop fifo passthru0
handle_a_interrupt: BUG, didn't clear interrupt. disabling.


I have scanned through ni_mio_common.c, but am none the wiser.

Could someone who has a better understanding of the driver better have a
look.

Thanks

Phil
