Panic - Watchdog Timeout: no checkins from watchdogd in 185 seconds

Most of the time I reboot my MBP 15-inch Mid 2014 with macOS Catalina 10.15.3 I get this... I tried PRAM and SCM reset but it comes back.

panic(cpu 2 caller 0xffffff7f88f3aaae): watchdog timeout: no checkins from watchdogd in 185 seconds (719 totalcheckins since monitoring last enabled), shutdown in progress

Bob, I came across this thread in search of a solution to this problem, which started to occur on my iMac 2017 since I installed the MacOS 10.15.6 update about 24 hours before. I didn't have the problem previously, but now it occured twice within 24 hours.

I also have a permanently connected external UBS drive that I use for TimeMachine backups. I had issues with that external drive when I upgraded to Catalina a few weeks ago as I had to disable sleep mode for hard disks to avoid the drive being constantly dismounted.

Not sure that helps in regard of "sharpening" your theory.
