My Kodicom 4400R Camera cards are not working after upgrading to 20.04LTS server

cn flag
AWM

These cards were working under a 16.04 server but that server died so I built up a new box running 20.04 and, when I install the cards, they don't work.

I was trying to view the camera with zoneminder but I had no luck. To troubleshoot the issue, I deleted the monitor in zoneminder (to ensure the device isn't being used), downloaded v4l-utils*, built v4l2grab and when I ran it, the saved files contain no images.

*I cloned the v4l-utils repo, cd to v4l-utils, checked out v4l-utils-1.18.0 (the version that is used by 20.04LTS), ran make (no errors), cd to contrib/test and ran ./v4l2grab with no arguments.

Here's the dmesg output from the time I first tried running v4l2grab since the system booted (there's more in dmesg between boot time and here but I can't post it now.

It looks like something in the v4l driver is crashing but I don't have enough knowledge to troubleshoot the issue myself.

Please let me know if I should post more information such as

  • more from dmesg
  • modinfo bttv
  • systool -vm bttv
  • v4l-info lspci
  • scanpci.gatos

or whatever else. I'll be keeping a close eye on this question for a bit.

You weren't specific as to what 20.04 product you're talking about (desktop? server? but mentioned 16.04 server then only 20.04) nor which kernel stack you opted to use (LTS releases come with two options), but esp. given it's an old card you want to use, did you use the GA kernel stack? (*I tend to find the older kernel stack better for older hardware as a general rule*) Being specific with details allows us to be more precise; but I don't know what you're using, so the only link I can provide is generic - https://wiki.ubuntu.com/Kernel/LTSEnablementStack

@guiverc Are you suggesting I try the following command? sudo apt install --install-recommends linux-generic-hwe-20.04 What happens then?

That would install the HWE stack and give you the option of the GA (5.4) kernel or HWE (currently 5.11) kernel to choose from, thus having different kernel modules (ie. *drivers*) available. However my suggestion was if you were using the HWE, the GA may better help you - you're already on GA; so it may not help - but key it may help anyway. The effect is just extra packages (you select kernel at `grub` and you can remove on stack if you so wish as per wiki page). Ubuntu Desktop defaults to HWE, Ubuntu Server to GA - you were already on GA which is what I suggest trying.

So the gist of what you are saying is that, because I am already on GA, which is already the older kernel, upgrading to an HWE kernel may or may not help me but I should try. Is that right?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
