Just hard-upgraded the sis's Mythbox to SuSE 11.3 (2.6.34) and Myth .23.1

And, of course, because I didn't do my homework, I'm getting the

*********************** WARNING ***********************
ivtv drivers prior to 0.10.0 can cause lockups when
reading VBI. Drivers between 0.10.5 and 1.0.3+ do not
properly capture VBI data on PVR-250 and PVR-350 cards.

error.

My ivtvctl says it's 0.10.5, in fact, and we're actually still locking the
machine.

My *question*, though, is this: how do you upgrade the actual driver now
that it's in the mainline? The ivtvdriver.org howto doesn't actually
cover this, and, at 2.6.34, I don't have a lot of kernel upgrading left
to do -- I would *really* prefer not to have to go off the reservation,
kernel wise, if I don't have to.

Can Andy or someone give me the 3 sentence precis of this, and once I've
got it done, I'll write it up for the wiki?

( Sorry this is poorly threaded, but my mailer won't let me at the
damn references header to unlink it... )

Cheers,

It has been years since I have debugged ivtv (it just works now!)
anyways I believe the kernel driver would be a recent version just
that the client applications ivtvctrl ... are ancient. Check your
dmesg to verify that. There should be the driver version in the ivtv
initialization line.

And I just did that, and to my surprise, while my *ivtvctl* is 0.10.5,
my driver is in fact 1.4.1.

It's not possible that the mismatched utilities package is what's causing
this, is it? I've been told that the utilities are supposed to Just
Match the driver, but clearly, Suse didn't get the memo.

In other news: why am I getting the backend error I am, if I'm on the
right driver? (I know: ask the Myth people. :-)

Cheers,

Does your machine provide any sort of Oops or BUG output in the logs
before the hang?

If it does I'd like to see it.

If it does not, odds are you have a Motherboard PCI Chipset / CX23416
PCI device incompatibility. If you haven't changed the motherboard and
the locking up is new, then it is likely the Linux PCI subsystem is
initializing your motherboard chipset differently with the new kernel.
(The ivtv driver has had a few changes, but I don't think they're
capable of locking the machine; making only the CX23416 act improperly
is more likely.)

Look at the output of

$ lspci -tnnvv

for all the PCI bridges between the CPU and the CX23416.

One can then check the history of the kernel's "drivers/pci/quirks.c"
code to see if any specific changes happened for you PCI chipset:

http://git.linuxtv.org/media_tree.git?a=history;f=drivers/pci/quirks.c;h=477345d416417c58662ea8386a0841ba65d0dd72;hb=9fe6206f400646a2322096b56c59891d530e8d51

If they have, try backing them out of your kernel.

Well the V4L2 API is pretty stable, so things shouldn't be too bad, with
a mismatch within a few years time.

Obviously using the latest ivtv-utils and v4l2-apps would probably be
best.

Dunno, what's the error?

If you kill the backend does:

v4l2-ctl -d /dev/video0 -i 0 <--- tuner input
ivtv-tune -d /dev/video0 -t us-bcast -c 7 <--- Channel 7
mplayer /dev/video0

Show you channel 7 video?

Andy
