Occured while running hikari on X11 with love2d and love2d on X11 directly
From original Summary:
BUG ON !list_empty(&fence->cb_list) failed at /wrkdirs/usr/ports/graphics/drm-fbsd12.0-kmod/work/kms-drm-99da0ba/linuxkpi/gplv2/include/linux/dma-fence.h:91
Hikari is a Wayland compositor. How can you run that on X11?

Via wlroots X11 backend. It works similar to Xephyr/Xnest but hardware-accelerated: running Hikari on X11 would create a window where one can manage Wayland and X11 clients according to Hikari rules. Such nesting isn't limited by depth but at some point performance may degrade e.g., on Skylake under Xorg "cage cage cage cage vkcube-wayland" runs with 60FPS but adding another "cage" drops to 45FPS.

Likely different panic/backtrace on the same radeonkms version. Confirming on 5.4-lts would be nice but until drm-fbsd12.2-kmod or similar appears it'd require upgrading to -CURRENT.
I opened this second ticket becase the error message is more explicit, i have quite a number of page faults but this one had a specific assert beeing triggered, so i do not consider it a dupe. :)
