Bug 282549: graphics/drm-kmod or graphics/drm-61-kmod
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=282549



--- Description ---
I am a bit out of my depth here, but this may be a bug in the drm-kmod system
according to what I have been told.  I am running FreeBSD 14.2-STABLE on a T16
ThinkPad.  Prior to upgrading to 14.2-STABLE this problem did not exist, but
since then I have upgraded my ports and that may be the reason.

Upon power up normally boot messages by the dozens scroll across the laptop's
LCD screen.  After the O/S upgrade (and many ports also upgraded) the laptop's
screen is blank -- no "login:" prompt, no final boot time messages.

It was suggested to me to try making a change to my /etc/rc.conf file.	This
change was to comment out this line:

   kld_list="amdgpu"

Then after rebooting the laptop, the boot screen was again "normal".  I don't
know how this change worked, or if it pertains to the drm-kmod sub-system, but
the person who suggested this change also suggested that if it worked, and it
did work, that I should submit a bug report, which I am now doing.  Thanks.
