https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231884 --- Comment #21 from johan van Zanten <johanvz816@giantfoo.org> --- dejacque:/var/crash # pkg info | grep drm drm-kmod-g20180930 Metaport of DRM modules for the linuxkpi-based KMS components drm-stable-kmod-g20180822 DRM modules for the linuxkpi-based KMS components libdrm-2.4.93,1 Userspace interface to kernel Direct Rendering Module services I've discovered an unpleasant side effect of the fix -- the kernel panics when i shutdown or reboot. It's after the "syncing disks" message. I can upload the vmcore from the crash if that'd be useful. This crash happens with the GENERIC kernel and a custom kernel i normally run (that removes a lot of devices not in my laptop). Below is the core.txt from one of the custom kernel crashes (the traceback is the same with both kernels). I can upload the kernel crash dump if that would be helpful. panic: page fault GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
