Dear Sebastian, tanks much for the time investigated into the problem analysis and designing solution. 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. I cannot send from my university account as well so I ma trying my company one if it passes -------- Forwarded Message -------- Subject: Re: Preemp-RT kernel builds from 6.3 on fails on Xilinx Zynq 7Z010 Date: Sun, 21 May 2023 16:42:13 +0200 From: Pavel Hronek <hronepa1@xxxxxxxxxxx> To: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> CC: Pavel Pisa <pisa@xxxxxxxxxxxxxxxx>, linux-rt-users@xxxxxxxxxxxxxxx, Thomas Gleixner <tglx@xxxxxxxxxxxxx> Dear maintainers, Thank you for looking into the issue.

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.
