Hi all together,
yesterday I installed 12.1-STABLE [1] with kernel version `uname -K` 1201519 on
my ThinkPad E490 with 'Intel UHD Graphics 620' [2].
But if I install the 'drm-fbsd12.0-kmod' and load the driver `kldload
/boot/modules/i915kms.ko` it will only show a black screen until I manually
poweroff the notebook.
See the `/var/log/messages` [3] below. The 'drm-fbsd12.0-kmod' from pkg [4]
behaves the sames as if I build it manually from ports. On 12.1-RELEASE it
worked just fine.
Has anybody a hint for me, what might be wrong and how I should deal with it?
Regards, Nils
