Yeah, it's also part of a larger changeset. But I wouldn't want to backport all those changes either. Attached is a simple patch for linux-stable that adds the necessary fix. If this still doesn't work, we should probably revert the problematic patch. Please test the patch and let me know if it works.Yes, this fixed the problem. I'm running 6.0.3 with your patch now, all fine.
Thanks a lot for testing. If Greg doesn't already pick up the patch from this discussion, I'll send it to stable soonish; adding your Tested-by tag.
Best regards Thomas
Thanks! AndreasBest regards ThomasI don't use git and I don't know how to /cherry-pick commit/ 9d69ef183815, but I found the patch here: https://patchwork.freedesktop.org/patch/494609/ I hope that's the right one. I reintegrated v2-07-11-video-aperture-Disable-and-unregister-sysfb-devices-via-aperture-helpers.patch and also applied v2-04-11-fbdev-core-Remove-remove_conflicting_pci_framebuffers.patch, did a "make mrproper" and thereafter compiled a clean new 6.0.3 kernel (same .config). Now the system doesn't even boot to a console. The first boot got me to a rcu_shed stall on CPUs/tasks, same as above, but this time with: Workqueue: btrfs-cache btrfs_work_helper I booted a second time with the same kernel, and it got stuck after mounting the root btrfs filesystem (what looked like a total freeze, but when it didn't show a rcu_stall message after ~2 min I got impatient and wanted to see if I had just busted my root filesystem...) I booted 6.0.2 and everything is fine. (I'm very glad! I definitely should update my backup right away!) I will try 6.1-rc1 next, bear with...
