Hauppauge WinTV-quadHD risc op code error

Ask Fedora

Hi all.

I believe this started after my upgrade from 40→41, however, I can’t be 100% certain, that’s just when I noticed it.

I’m receiving constant, non-stop, spam errors in my dmesg (and syslog) regarding a Hauppauge WinTV-quadHD video card (PCIe).

These:

On the cx23885 driver I have set dma_reset_workaround=2

That didn’t change anything as far as I could tell.

If I reboot the server with the cx23885 module blacklisted, no issues. But once I modprobe cx23885 it’s non-stop errors.

I have used this card for 3 years without issues, no one has physically been inside the server, so I don’t think it’s a hardware outage/break.

I’m considering filing this as a bug but thought I’d seek any advice here first and make sure I’ve troubleshot all the angles first.

Thanks for any help!

The software is constantly being upgraded, and the most recent kernel update for both f41 & f42 was the kernel 6.17.4

I suspect the driver in use may not be compatible with the newer kernel and probably needs updated.

It appears that driver may be part of the libv4l package, so check if that package is fully up to date. If not then possibly a bug report should be created.

To find out what version you have for that driver the command modinfo -F version cx23885 should tell you. On my system (f43 Workstation) that command returns 0.0.4 and I have libv4l version 1.32.0-1.

Thanks Jeff.

As of yesterday (and still having the issue), my f41 kernel is 6.17.6, libv4l version is 1.28.1, and cx23885 is 0.0.4

I’ll look into libv4l and see if there’s anything related that may be fixed in 1.32.0
