When I booted the 6.19.10 kernel in a Fedora 44 KDE installation, I 
pressed the escape key while plymouth was shown. I noticed an error in 
the plymouth detailed output
[drm:drm_mode_config_cleanup] ERROR connector Unknown-1 leaked!


There were warnings and errors in the journal when amdgpu started during 
boot involving drm_mode_config_cleanup and plymouthd to begin with 
followed by some others.

These warnings and errors occurred on every boot with 6.19.10, but they 
didn't happen with 6.19.9 or earlier. The problem also happened when I 
didn't press escape when plymouth was shown. The plymouth screen 
appeared to reset while the spinner theme was shown. I haven't seen 
other effects of the problem. I could try to bisect. The commit 
e493c135980f90c20308d1a98f2e0d1223951e94 drm: Fix use-after-free on 
framebuffers and property blobs when calling drm_dev_unplug was included 
in 6.19.10 and changed drm_mode_config_cleanup 
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-6.19.y&id=e493c135980f90c20308d1a98f2e0d1223951e94

This problem happened with 7.0.0-0.rc5.260325gbbeb83d3182ab.44.fc45 and 
the virtio-gpu driver in a Fedora Rawhide KDE live image 
Fedora-KDE-Desktop-Live-Rawhide-20260327.n.0.x86_64.iso in a QEMU/KVM VM 
in GNOME Boxes. So the problem wasn't specific to amdgpu. This problem 
also happened with 7.0.0-0.rc5.260325gbbeb83d3182ab.44.fc45 and amdgpu 
on bare metal.

I reported this problem at 
https://bugzilla.redhat.com/show_bug.cgi?id=2452563 and 
https://gitlab.freedesktop.org/drm/amd/-/work_items/5114 I'm attaching a 
kernel log.
