Hi,

I have an issue I've been seeing since Catalina rolled out on my 16inch MBP.
I don't see it on my 15inch MBP.


This issue:

On trying to reboot Catalina (the issue never occurs during use, only on reboot), after some time in use not always, the reboot process takes 5/6 minutes, then I see an error like this when the system comes up:

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


It's infuriating.

Many folks seeing the issue:

It's so annoying, I have tried everything, SMC reset, PRAM zap, checked loaded Kexts using `kextfind` and compared across multiple machines, not using any non-apple kexts.

I have applied combo versions of 10.15.6 (19G73), etc etc, it keeps occurring randomly.

I also have windows installed using bootcamp, and see no issues ever on reboot.


Is a full OS reinstall the only solution? I don't even believe it will stop the problem...
