[linux-dvb] cx23885 driver and DMA timeouts

The card works perfectly using Chris Pascoe's branch, I can use both
tuners at the same time. It only stuffs up when I try and merge the
relevant sections into tip, as per the patch I attached in the previous
email. So this eliminates bios/hardware faults. I can also try in
windows for you, but I'm sure this is not the fault.
I would like to run a more modern version of the hg code as I have other
cards sitting around that could go in the same system and also I fear
that if somebody doesn't do the work to get it into tip, support will
disappear for newer kernels.
Thanks for help, any further advice?
(Also you lost me a bit with sram and risc, is this for the
microprocessor on the tv card or is it on my motherboard/cpu? And do you
have any documentation about them so I can learn more about it?)

If the vidb and vidc (ts1 / ts2) bridge streams each single channel
correctly, but not both together then this is either a sram
configuration issue (the risc engine's workspace is being corrupted
by another risc channel), or your system has a pcie compatibility
I've seen both of these issues in the past.
I don't have a hardware product with demodulators on vidb and c, so
that's not something I can repro.
Can you dual boot the same system under windows and remove any pcie
