[SOLVED] Xorg lockups intel

Hi

Since yesterday or today, I've hit a Xorg display lockup a few times on my Intel NUC (possibly since kernel 5.10.4).

Display is black, keyboard no longer works.  I can still login through ssh, but Xorg is unkillable, even with kill -9.  "poweroff" kills my ssh session, but it does not shutdown cleanly, I have to pull the power.
Anyone else experiencing this?

journal shows repeatedly:

INFO: task Xorg:4365 blocked for more than 122 seconds.
      Tainted: G     U            5.10.4-arch1-1 #1
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
