I'm using a Nebula DVB-T card with the bt878 driver and kernel 2.6.8.
When MythTV is recording, the bt878 driver seems to generate several
hundred log messages per second, like this:
Aug 26 17:04:39 bluebox kernel: bt878(0): irq FDSR risc_pc=1eb84210
Aug 26 17:04:39 bluebox last message repeated 523 times
Aug 26 17:04:39 bluebox kernel: bt878(0): irq FDSR risc_pc=1eb84010
Note - all that in less than a second.
Looking at the code for the bt878 driver it appears that turning off
"bt878_verbose" might reduce this, but is it normal? It seems odd to
want to produce quite so many log messages.

I've seen something similar with my DVB-T card - it was then that I
realised that I'd not compiled IDE DMA support into the kernel. The
DVB-T card is probably not getting a response to its interrupt quickly
enough because the system isn't running quite as it should.
Hope this helps some.
Justin.
