Bug 259455: graphics/drm-devel-kmod: loading i915kms from rc.conf cause system
freeze
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259455



--- Description ---
On my Lenovo Thinkpad T490 system freezes while loading i915kms (both
drm-devel-kmod and drm-current-kmod) from rc.conf as port's description
suggested. This on latest 14.0-CURRENT. System boots normally when:
- goes into single user mode, waits about 10 seconds and exit single user mode
or
-load i915kms from /boot/loader.conf instead kld_list in /etc/rc.conf
or
- boot when dock station with external monitor attached


FreeBSD 14.0-CURRENT #12 main-n250238-dfd704b7fb2-dirty
drm-devel-kmod-5.5.19.g20211013 from ports

Thank you.
