I've spent enough time on 6.11.0-18-generic to be convinced the issue does not reproduce anymore. ** Changed in: linux (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2095100 Title: kernel panic when setting application in fullscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2095100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2095100] Re: kernel panic when setting application in fullscreen
So it took me a bit more time but there was also a UEFI update coming through, moved to 6.11.0-18 from oracular-propposed a few days ago. Since, I have been able to use everything as before, and especially tried multiple times to play fullscreen videos with success. Usually it would fail after a few hours. Given the STRs being unclear, I cannot yet declare victory, but things looks much better. So at that point, two options IMHO: - the issue is some resource exhaustion that was caused by a third party (e.g. firefox) and that got fixed in parallel (I run nightly) - some fix made it between 6.11.0-13 (from the initial report here) to 6.11.0-18 that I am running as of today. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2095100 Title: kernel panic when setting application in fullscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2095100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Wanted to edit an image in GIMP, happened again. Tried to get 6.13-rc to boot, but with SecureBoot it's painful and too much time consuming for me right now to setup something that works. I've kept /lib/firmware/amdgpu to reflect the origin/master of current linux- firmware repo, though, so maybe it's fixed by a firmware change? We'll see. If the mainline kernel were provided with secureboot signature that would be easier to test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2095100 Title: kernel panic when setting application in fullscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2095100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2095100] Re: kernel panic when setting application in fullscreen
Yes it's easy as putting something in fullscreen, but as mentioned earlier when I tried to get solid STR to make sure I could give a straight answer whether it fixes, then I had difficulties. At some point it reproduced but I don't know why at that moment I hit it. So anything that I need to test should be a change I can use as a daily driver since it may take hours / days to confirm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2095100 Title: kernel panic when setting application in fullscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2095100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm not suggesting you to keep using/maintaining such a kernel, it's a
debugging data point to prove whether the MST fixes I'm talking about
helped. If they help perhaps Canonical can do the backport.
Aaron can also potentially give you some test kernels if you can't
compile.

It will fill up your logs (and thus your disk) leaving it on. From your
description ("anytime I set an application in fullscreen mode") I was
under the impression this was easy to reproduce (IE just full screen an
app with the monitors connected). Is that not the case?
If it's that easy to reproduce maybe Aaron can try too.
> If there's a kernel from 25.04 (assuming it's 6.13?) that could be

Not that I can tell.

[Bug 2095100] Re: kernel panic when setting application in fullscreen
From the trace this is triggered from a userspace IOCTL to remove a framebuffer. This causes drm core to process atomic_remove_fb() as work, and this will use the drm driver to do atomic modesets. One of the things that happens for this is going to be recalculating MST DSC configs (if appropriate). You can see more about this in compute_mst_dsc_configs_for_link(). Returning -ENOSPC I would guess happens as part of drm_dp_mst_atomic_check() meaning the atomic check failed. I think this should be debugged in two ways. 1) Try a mainline 6.13 kernel. I know for a fact we had a variety of MST/DSC fixes that have gone in since 6.11.0. Most of them are in stable 6.11.y and 6.12.y, but the Canonical kernel isn't tracking stable. Unfortunately; it seems that the Canonical kernel PPA is effectively dead, so you'll have to compile this yourself. 2) Turn on dynamic debug for DRM (drm.debug=0x106 on kernel command line) and turn up log buffer length (log_buf_len=50M). Then there will be some more messages that come in (for example the debug message in drm_mode_rmfb_work_fn()) and compute_mst_dsc_configs_for_link(). This will help give more hints where the -ENOSPC is coming from. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2095100 Title: kernel panic when setting application in fullscreen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2095100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
