>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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2095100 Title: kernel panic when setting application in fullscreen Status in linux package in Ubuntu: New Bug description: Since 24.10, on amdgpu device (AMD Ryzen 7 PRO 5850U), anytime I set an application in fullscreen mode (video player, firefox, signal etc.) I end up with this crash.
