Doesn't this just ignore the errors? Admittedly that might not be a bad
solution (although you will get some corruption when it occurs).
The thread that the OP mentioned discussed interaction between the BT878
and sata drivers. For me the problem was much worse when I started
streaming to SATA disk, but I had seen it on occasion before that. But I
do recall that it seemed better in earlier kernels (around 2.6.3?).
Maybe there is longer interrupt latency for some reason in newer
I'm now running a budget-ci card (SAA7134?) plus two cx23883s and it all
