Apple Event: May 7th at 7 am PT
I updated to 11.2 today and since then it seems like when it goes to sleep I get panics and restarts.
Sleep transition timed out after 35 seconds while calling power state change callbacks.

Are you connecting your M1 MBP to any sort of dock by chance?
I'm at wit's end with this exact wake-from-sleep kernel panic. I thought it was originally related to using my M1 MBP with a CalDigit TS3+ Thunderbolt Dock, but it just happened when I reconnected my MBP to a Thunderbolt Display on one TB3 port and to an OWC USB-C travel dock on the other (2 SanDisk Ultra flash drives were connected to the dock).
I've completely reinitialized my machine via DFU restore and set it up from scratch (i.e. I did not migrate from a backup), and this is still happening. I've even filed a feedback report: FB8969561.
This has been happening since I received the M1 MBP in mid-December, Mac OS 11.1. It checks out fine using the built-in diagnostics. I haven't experienced this degree of instability since the pre-OS X days.
Once again it appears that Apple's hardware is ahead of its software. I would really appreciate it if Apple could fix these kernel panics.
On the M1 Macs, the wake transition times out after 35 seconds, not 180 (3 minutes).
I strongly suggest that you open a case with Apple Support if you want this to be fixed.
