I have a couple of Hauppauge cards (Nova-T using
the cx2388x and a Nova Plus, again using an cx2388x) in an industrial
motherboard (an Axiomtek ATX6022-14G) which is causing me some grief. After a
short time I am getting both cards locking up (no DMA) at the same time.
In order to get these cards working at all in this
configuration, I have re-arranged the SRAM and increased the FIFO size in
cx88-core.c to 0x4800 bytes, and disabled all the other channels (video,
audio etc), which has cured the FIFO overflow errors I was getting ( general
errors: 0x00000100), but the cards still lock up. The cards can run from between
5 seconds and 30 minutes before the lockup. I also get the lockups with the
stock code, so I am happy that my SRAM chganges have not broken
anything.
I am using the latest hg code and kernel
2.6.23.8
The processor is a Intel(R) Core(TM)2
CPU 6700 @ 2.66GHz
I have tried the system with maxcpus=0 and
maxcpus=1 kernel parameter with the same results, so it is not an SMP/locking
problem as far as I can tell.
I have tried changing the pci latencies using both
setpci and by changing the module paramers from 0 to 128, again with no real
change.
Just before the lock up, there is a cx88 timeout,
(DMA or PCI locked up maybe?). As far as I can see, the timeout will almost
always result in the cards stopping. The rest of the system runs fine, and a
module unload/reload usually puts things right.
The relevant part of the syslog messages looks like
this, though I have added few more printks to try to see what is
happening.
Sometimes, the RISC dump contains INVALID opcodes,
though I don't understand enough about the RISC controller at the moment to say
whether this is important or not.
It looks like after the restarting of the queues,
the DMA does not start.

I am now stuck, so can any of the cx2388x experts
point me in the right direction to track this problem down?
If you want a more complete dump I can mail
privately.
