[Bug 260890] graphics/drm-fbsd13-kmod: display artifacts in xorg (Intel HD Graphics 3000)

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260890

--- Comment #9 from Benjamin Stoker <benrkts@yahoo.com> ---
Ok, fresh install of 14.0-CURRENT running xorg, modesetting, i3-gaps, mpv, and
qutebrowser, and I can report that:

1. drm-current-kmod (5.4.144) does NOT work.  Not only are there frequent
artifacts as described above, the GPU hangs every few minutes, giving messages
such as:

kernel: drmn0: GPU HANG: ecode 6:1:0xc3c3c3c2, in python3.8 [100291], hang on
rcs0
kernel: drmn0: Resetting chip for hang on rcs0
syslogd: last message repeated 12 times
syslogd: last message repeated 15 times
kernel: drmn0: GPU recovery timed out, cancelling all in-flight rendering.
kernel: drmn0: Resetting chip for hang on rcs0

2. drm-devel-kmod (5.5.19) works VERY well.  Performance is great, there are no
hangs, and after several days of testing I am unable to trigger the bug.

If you want further information let me know.  Otherwise, I will be going back
to my 13.0-RELEASE partition, so consider this a request to make the newer
drivers available in the next release.
