Bug 285398: graphics/drm-515-kmod
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285398



--- Description ---
I'm running 
 FreeBSD 14.2-RELEASE-p1 GENERIC amd64
(upodated from previous Minor-Version)

# freebsd-version -ku
14.2-RELEASE-p1
14.2-RELEASE-p2

WHAT I DOING:

I compile drm-515-kmod from Ports to get the graphics working:

# git clone --branch releng/14.2 https://git.FreeBSD.org/src.git /usr/src
# git clone --depth 1 https://git.FreeBSD.org/ports.git /usr/ports
# cd /usr/ports/graphics/drm-515-kmod/
# make package

After this successful compiled/created:
# pkg add work/pkg/drm-515-kmod-5.15.160.1402000_3.pkg 

# pkg info drm-\*
drm-515-kmod-5.15.160.1402000_3

WHAT IS THE PROBLEM:

After running the command
# kldload amdgpu

I get a black screen and the computer freezes (even ping the computer no longer
works; neither does SSH).
After a short time, the PC reboots automatically.

After booting up, I check the /var/log/messages
An excerpt of the log can be found in the attachment

There is no Kernel-Crash-Dump in /var/crash
(and Crash-Dumps working; I've tested it with sysctl debug.kdb.panic=1)

Similar behavior with graphics/drm-61-kmod, with the exception that there is no
automatic reboot.

I would be happy to receive feedback. If any additional information is needed
or if I should try something, please let me know.
