Pavel Hronek has checked actual daily runs of for-kbuild-bot/current-stable of https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel and manually tested your 6.3 RT version and reports that is is stable now. But he has problem that his e-mail didnot pass mailing list filters rules. I am trying to resnet from my other e-mail.

The last two rounds of automated tests on 6.4.0-rc2-rt1 (https://canbus.pages.fel.cvut.cz/can-latester/inspect.html?kernel=rt&flood=1&prio=1&kern=1&load=1) have completed without the lockup and the messages no longer appear in the console. I've also run the tests manually on 6.3.3-rt15 and the same workload that would freeze an earlier version of 6.3 within a minute has now lasted for over 30 minutes before I stopped it. No warnings here either. I think I can confirm the problems are gone.
