Kernel Panics after upgrading to Big Sur

My 2016 MacBook Pro 15" was completely stable when running Catalina but now crashes frequently with a kernel panic when going to sleep.


I have reset PRAM, SMC etc, run diagnostics in Internet Recovery. Diagnostics says nothing found. No kernel panic log is found Library/Logs/DiagnosticReports.


Attached is the Kernel Panic copied to a text edit doc from the send to apple screen.



Any ideas?


Thanks,

An update to this post. This MacBook Pro just came back from AppleCare with a new Logic Board, and Top Case with battery. The Kernel panics have returned and continue when the MacBook Pro goes to sleep.


I still tend to think that this is a Big Sur issue as it never occurred with Catalina. The software and kernel extensions are the same as the ones I had running in Catalina.


The kernel panic from the alert dialog box always points to "Suspected bundle: com.apple.iokit.IOUSBHostFamily" Does this offer any clues?


Thanks
