Hey, all...
I've been trying to track down a periodic hang in a PVR-350 box,
and I wanted to bounce a few thoughts off the group. I suspect
the motherboard is the culprit, but I want to get a second
opinion before I go to the trouble of replacing it.
My system's vitals:
PVR-350
P4 2.4 GHz
ABIT SG-72 motherboard (SiS chipset)
Linux 2.4.27
Current ivtv version: 0.2.0-rc3a
(Complete boot-up logs cut & paste below.)
The problem is that periodically, during capture, the encoder
freezes up. Specifically, data stops arriving on /dev/video0.
This happens about once per 4 hours of recording.
There seem to be two primary failure modes. In one mode, the
process reading /dev/video0 is killable, and doing ivtvctl -H
(to reload the firmware) after killing it brings everything
back to life. In the other failure mode, the process reading
/dev/video0 is unkillable, ivtvctl -H hangs, and the only
solution is a reboot.
Regardless of the failure mode, I don't see anything in the logs
at the time of the failure, so I have no hints as to what is failing.
After a "hard" failure, attempting to kill the process reading from
the device produces messages like the following in syslog:
Dec 27 14:20:09 mythos kernel: ivtv: ENC: User stopped capture.
Dec 27 14:20:19 mythos kernel: ivtv: 1000 ms time out waiting for firmware

0xfffffff0

Dec 27 14:20:39 mythos kernel: ivtv: Failed api call 0x000000c6 with result
0xfffffff0
It's worth noting that I'm getting _lots_ of errors reported in
/proc/interrupts (even when the system is working "normally").
The errors seem to be accumulating at a rate of about 5 per second
of uptime.
# cat /proc/interrupts

15: 4 XT-PIC ide1

Are IRQ errors like this normal?
Is it possible they're linked to the periodic firmware hangs?
Has anyone else seen symptoms similar to mine?
Has anyone else had problems with an ABIT motherboard or SiS chipset
that were resolved by changing motherboards?
I'd also like to know what's happening at the moment the firmware
is dying. It bothers me that the logs show nothing at all at the
moment of failure. Can anyone recommend debugging options and/or
ways of instrumenting the driver that might shed some light on the
problem?
Other information:
1. When I first installed the PVR-350 in this machine, I got the
following console message repeatedly during capture:
APIC error on CPU0: 40(40)
I had to disable APIC in the motherboard's BIOS to get rid of the message.
Currently, I have APIC options turned off in the kernel as well,
though this doesn't seem to make a difference.
2. It could be my imagination, but it seems like crashes are more
common when the machine is doing other high I/O operations (such
as lots of disk access) at the same time.
Thanks...
