Would it be possible for you to check as well directly vanilla upstream 4.19.181 and ideally 4.19.183 and if reproducible try to bisect the offending commit introducing the issue? https://wiki.debian.org/DebianKernel/GitBisect might help here. It might be related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1901089 and 896111dc4bcf ("media: rc: ensure that uevent can be read directly after rc device register") from 5.11-rc6 but which was backported to 4.19.173 and 5.10.13. Do you have the same problem running the backports kernel? Regards, Salvatore
