My PVR system uses two PVR-150 MCE cards. I am repeatedly getting "silent hangs" on my up-to-date Debian Etch system, which has a VIA-based AMD64 motherboard. The only non-Debian executable is the latest lirc from the upstream source. I don't have any reason to suspect ivtv, except that it's probably the newest driver I am using, the continuing bug reports here, and the fact that mythtv crashes or exhibits other anomalous behavior under heavy load.
The sole symptom is the apparent lost of the root partition, which therefore leaves no logged evidence of the failure. making it difficult to track down. (It may even rule out crash dumps.) I don't think the hardware is unstable because I have tested using many 10s of kw hours at 100% I/O and CPU load, with 100% failure detection. Significantly, the only hardware the doesn't get excersized in the tests are the PVR cards, which again could point to ivtv. The other clue is that mythtv behavior changes when I switch kernels. Under 2.6.18 mythtv just crashes, while under 2.6.23.1 it keeps running but no video comes out of one device, but the other keeps working.) I suspect that every hang occurred when at least one of the PVR cards was in use. Thanks for any ideas or help.
