iMac/Big Sur
My new M1 iMac running macOS Big Sur 11.5.2 keeps having "panic attacks" which cause it to re-boot. I have reported this to Apple many times and spoken at length to Apple Support who basically just suggested re-loading Big Sur which has changed nothing. The message box containing the re-boot information says:
"panic(cpu 0 caller0xfffffe001f124c10): Wake transition timed out after 35 seconds while calling power state change callbacks. Suspected bundle: com.apple.driver.usb.AppleUSBHub. Thread 0x9e1a. Debugger message: panic"
and so on for another 6 pages. It is not always "cpu 0", it varies.
Has anyone else experienced this problem?
