I'm using CONFIG_HZ=250. I have tryed also CONFIG_HZ=100, but it didn't
helped.
Ihave tryed to remove one of the four tuners and now I have no shared
IRQ, but the PC still freeze. It is bug in DMA or whats wrong?

Yes, I'm using xawtv + overlay directly to the X display :0.0. Is better
way to use it with some WM (KDE, Gnome, ...)?

On the mainboard is graphics card Intel 915. I have tryed it with i810
(with / without DRI) and vesa driver. I have also tryed PCIE graphics
card from ATI. In all of those cases the PC freeze and as well as if is
in PCI slot only ONE tuner!

I'm totally lost! I have here 25 PCs (100 tuners) what always freeze ;o(

Try using grabdisplay. Also, if you hook up a serial console you may see
some helpful output when the pc freezes.

Hi,
I think, it's problem in XAWTV, because I've got the same error if I
had only one TV tuner in my PC. I've solved the problem that I reduced
number of items in channel list. If I have in the list only 10
channels, then any of the four XAWTV didn't crashed. It's very
strange. It looks like the pop-up menu with the channel list write to
the memory of the graphics card somewhere out of the memory. What do
you think about it?

I didn't change xawtv configs, and
1) with the patch system did not crash
2) without the patch system crashed
draw your own conclusions.
and
3) if xawtv is able to crash kernel, kernel needs fixing.

OK, I will wait for the change in the kernel.

It is strange, but manipulation with the channel list (longer then 15
items) in XAWTV made not only solide lock of the kernel, but also
sometimes only crash of the USB driver or PS2 keyboard driver. I think
there is (was - not with your patch?) something wrong in the kernel.
Maybe some memory problem.

I've tryed to apply your patch and tested it and I've got the same
result like without your patch - by manipulation with the XAWTV channel
list the PC crashed and I've got in the /var/log/message this:

I'd appreciate if you didn't delete the Mail-Followup-To header.
Also, I don't need a personal copy. That's exactly why there's no my
email in Mail-Followup-To.

It was made by Duncan Sands.

Sorry to hear about your crash.
I suggest that you wait till Duncan or somebody else
releases the "final" patch.

FWIW, I have a box (with only one bttv card) which does not work stable
neither due to the capture card. It DID run stable at one point, but I
think that was kernel 2.2-ish... I tried quite a few things, IIRC when
it did run stable I had to tweak pci latency timer in the bios, but this
no longer works. Tried kernels with/without apic, acpi, smp,...
I also get the same OCERR error messages, and very similar oops. Though
it usually locks up only once every few hours or even days. Sometimes
hard and sometimes soft lockups.
The bttv driver/chip seems to cause random memory corruption sometimes,
processes will just start dying... My guess is that somehow dma
transfers to random / wrong addresses happens when there are lost irqs /
pci bus contention, either due to a driver bug or a chip bug (something
like losing parts of the risc program) though if there is a chip bug,
that behaviour never happened with some other OS so a workaround should
be possible), but I could be ways off.
This was with a i440bx chipset btw, it runs just fine with a newer box
(though overlay had problems there too, but since the box is faster I'm
just using grabdisplay, which didn't do anything for stability on the
old box). Tried both a bt848 and bt878 card which didn't change anything.

There is a known buffer overflow in the bttv driver (when using
grabdisplay). The fix is waiting on an audit of the rest of the
bttv (and similar) code, since it looks like the same mistake
occurs in several places.
Ciao,
