Generally, the VIA problem is restricted to the kt133/266 chipsets,
and I believe it has even been worked out in any kernel from the last
year.
I had a hell of a time with NFS for a while, as the upgrade to OS X
10.4 on one of my front ends would lock the backend up after only a
few hundred KB transferred. It was fixed by switching from sync to
async on the NFS server export.
As far as asking the ivtv list fro help, I doubt your problem really
lies with ivtv.
You could also research your interrupts. Look into noapic and
nolapic as well. Something might work.

Hello,
I'm not 100% certain this is caused by ivtv, but this list wins the
friendliest/most knowledgeable contest, and the prize is my question.
I have an AMD64 machine running Debian sarge with 2.6.11.7, in 32
bit mode. It's sole purpose is to run mythbackend (.18). It has a
single PVR-500MCE with ivtv 0.3.6e. I have a second PVR-500 I'd
like to add, but am trying to resolve this problem first. One
possible problem is my MB has a VIA chipset. It is an MSI K8T Neo2-
F (I was looking for AMD64 with a good number of PCI).
The problem is it reboots spontaneously. There is nothing in the
logs, I even had the kernel use ttyS0 as the console, and had
another machine capture the output. Still nothing interesting. It
seems to happen more frequently if the machine is busier. I
haven't seen a reboot when it records a single program at a time,
for weeks on end. But if I am viewing something prerecorded (over
NFS) while it is recording, it is very likely I will get a reboot
within 30 minutes. I don't remember any reboots when I just view
prerecorded video while it is not recording.
This has occured with older versions of the ivtv driver, and
although I am now using the firmware that came with the card, I've
also had problems with 0x02040011. I am not using any module options.
My questions: Is there a better way to determine what is going
wrong. Console to the serial port didn't capture the error, and the
machine reboots so fast, if I sat and watched the monitor, and it
did say something, I doubt I would be able to read it. I've also
read posts on this list that there people have had problems with
VIA chipsets. Does anyone know if these same problems happen with
these chipsets under Windoze? If not, would it be that Windoze
isn't as demanding of the chipset as linux is, or more likely the
linux drivers have problems because VIA doesn't give OSS developers
the datasheets they need?
I'm going to try 2.6.12 now and see if that makes a difference. I
read something in the changelog about changing the way interrupts
are handled with VIA. I couldn't tell it that was relevant to my
situation, but it can't hurt to try. If anyone has suggestions on
how to narrow this down, before I have to buy a new MB, I'd
appreciate it.
Thanks,
-Michael
