Re: [ivtv-devel] System hangs loading driver modules for PVR-500

Here is dmesg after taking the PVR-500 card out and putting in a PVR-250 (that works).

None of these messages show up in dmesg when the PVR-500 is installed.

Subject: System hangs loading driver modules for PVR-500

I am trying to run a PVR-500 in a Dell 2850 server on CentOS 4.3 (basically like RHEL 4.3, as I understand it).

The PVR-500 works fine in my desktop PC (HP m7360n). Both systems are dual core, so I’m running the SMP kernel 2.6.9-34.0.1.ELsmp.

The Dell 2850, CentOS 4.3, and ivtv drivers work fine when I use a Hauppauge-modified PVR-250 (modified for PCI-X).

Hauppauge said the PVR-500 does not require modification for PCI-X, so I installed it as-is.

lspci shows PVR-500, with two entries (one for each tuner).

I’ve gone through all of the steps of several how-to’s, including the detailed how-to on ivtvdriver.org. I’ve tried using ivtv RPM’s installed via yum (worked with the PVR-250), and I’ve also tried building the drivers from the latest 0.4.5 source from ivtvdriver.org download page. And I’ve read through the docs as best I can understand them.

When I get to the step:

modprobe ivtv

The system locks up completely. I have to hold down the power button to shut it down. The 2850 has a status LCD on the front with an error code. (Let me know if that’s useful to anyone.)

I didn’t see anything useful in dmesg. It never talks about IVTV or anything. It does list the IRQs, but never starts processing the IRQs for the 2 tuners.

Right now, the system won’t even boot anymore. If I take the card out it may boot, but I’m too tired after spending all day on this so far. I’ll do that tomorrow. But early in the boot cycle now, when it says “Recognizing hardware” (I think), it shows “audio” and two other things, and then pauses about 10-20 seconds, then the status light goes amber and it’s dead. That pause and then death is the same thing I get when I run modprobe.

I also tried creating the /dev/videoX devices myself (instructions are in the ivtv docs directory). The mknod worked, but when I tried to change the owner of the file from root to someone else, it hung.

I’m stumped.

By the way, my goal is to put 3 PVR-500 cards in the 3 available PCI-X slots, and read vbi data from /dev/vbi. What numbers will it use after /dev/vbi3? I think vbi4 is taken. The docs say ivtv can support up to 12 cards right now.

Thanks,

Rich
