Big Sur Panics on Sleep. Happened on Catalina as well. Over and over again...

13" MBP. Wiped machine, clean install, reset the pram, etc etc.

panic(cpu 0 caller 0xffffff8011e8915a): Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.driver.AppleIntelFramebufferAzul. Thread 0x280c.

Failure code:: 0x00000000 00000014

Also locks up with App Store and sometimes with Safari.

Any ideas?

(BTW If you say "Safe Mode" then please say what to do in safe mode to diagnose or fix things... safe mode on its own is not a panacea).

MacBook Pro 13″, macOS 11.1

It's not a fix, but if you start in safe mode and the panics go away, that implies that it's a system extension or kernel driver that's at fault, not the OS itself.

So restart in Safe Mode and see if the panic continues to occur.

A workaround for many who have had this is to disable PowerNap.

Be patient ... FWIW macMini 2018 users had firmware related sleep related kernel panics in Mojave eight months from March to November 2020 until the Big Sur 11.0.1 firmware update (and AFAIK the Mojave security update a few weeks later) fixed it. Apparently that bug was then transferred to MacBook Pro 13"... I am now unlearning a habit to shutdown instead of sleep and to use Safari (that always triggered to crash) instead Chrome.
