Why is the [shutdown_stall] error back on my MacPro (late 2013) updated to Monterey 12.2.1?

What is causing this problem to keep recurring? The scheduled AM starts and PM shutdowns work fine, but my monitor screen stays blank. I have to push the MacPro power button two or three times to get the monitor to wake.


One monitor wakes, the logon screens comes up, I log in and all is well.


HELP!

Try booting to Safe Mode. That boot up takes minutes and clears caches and other things that may resolve your problem.

A lot of times just boot to Safe Mode followed by normal boot resolves problems.
