Hmmm.. Well I've done some more testing and it seems my computer is
still rebooting randomly. Maybe I'm not tuning the tuner correctly?
I'm using:
pvr250-setchannel -m 2 5
I noticed if i add the -a on option, then read from cxm0, I get "cxm0:
missing encoder EOS" in /var/log/debug.log and no output. I have to
unload the cxm driver and reload it to get cxm0 to work again.
The -t option seems to work fine.
If I read from both cxm0 and cxm1 at the same time, the reboot seems
to come alot sooner, and debug.log has alot of the "encoder dma" error
messages:
Apr 6 23:37:15 unf kernel: cxm1: encoder dma not enough buffer space free
Apr 6 23:37:15 unf kernel: cxm1: encoder dma not already in progress
Apr 6 23:37:15 unf kernel: cxm0: encoder dma not enough buffer space free
Apr 6 23:37:15 unf kernel: cxm0: encoder dma not already in progress
If I read from just cxm{0,1}, I get a few "encoder dma" error
messages. Most of the time, they just appear when the read is starting
and ending.
I had mythtv working so well for an hour or two!! *sighs*
