Yes, I did. The bugs first caused problems and were noticed right
away after 11.2 was released.

Yes, I can. Do you want them on this list? Or somewhere else?
When I looked for a PR, I couldn't find one either. I had assumed that
multiple PRs had been filed for the various problems back when 11.2 came
out, but apparently that wasn't done. My system is currently running
without xorg due to a GPU crash in gpu-firmware-kmod, combined with an
inappropriate response by drm-fbsd11.2-kmod (/boot/modules/radeonkms.ko
does a BIOS reset in an attempt to do a hard reboot), so I doubt that I
can file a PR. Another poster offered to file PRs for me in the interim,
and I sent him a description of the x11 problems, but I didn't hear back
from him. I was waiting to send descriptions of the memory management
problems until the first two x11 PRs had been filed.

That is correct. They afflict systems running FreeBSD 11.2 to the
present of 11. I am now running stable/11 at
FreeBSD hellas 11.4-PRERELEASE FreeBSD 11.4-PRERELEASE #24 r360432: Tue Apr 28 18:48:15 CDT 2020 bennett@hellas:/usr/obj/usr/src/sys/hellas amd64
and the problems are still present. Everything in 11 from 11.2 on is
unsuitable for use on a production system because it has to be rebooted
frequently in order to keep it usable.
