The ivtv driver is giving me some grief. Besides the error messages about "ENC
DMA ERROR b", sometimes the machine will hang, leaving the message "ivtv0: DMA
TIMEOUT 00000001 0"
Is ivtv .10.3 working well for everyone else?
I'm looking for advice on how to workaround this problem. I've included
excerpts from /var/log/messages and other info that could be useful.
