When I boot into the old kernel, 5.11.0-38 it is still working. I found that this issue has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=214455 and it could be traced back to commit: 3f38cc1ba1e289306f52cb7238406f38ecbfa21a net: qrtr: make checks in qrtr_endpoint_post() stricter which was also in the patchset: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1946788 for the 5.11.0-40 release. in the bugzilla link a solution was mentioned and it generally doesn't seem too big a problem, would be awesome if someone could look into this.
