There are two tickets in launchpad related to this same issue:

https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.14/+bug/2125337
https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.14/+bug/2115983

I am not sure how we should approach this issue, but I'll try to figure out the best solution.

It seems that updating the udevparser to ignore the ipu drivers could solve the issue.
We could change the filter:
"intel[-_]ipu[0-9][-_].*" -> "intel[-_]ipu[0-9].*"
This change removes the extra ipu devices from the "CAPTURE" list
