Kernel Panic every time I close computer

I just updated to the latest version of Big Sur (11.6.4). Suddenly, every time I close and then reopen my computer, there is a kernel panic. I tried rebooting in Safe Mode and the problem is still there. The particular error message says "Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.driver.AppleIntelICLLPGraphicsFrameBuffer."

Thanks for the clarification.


I am nearly two days in post-Monterey upgrade and my MacBook is still completely stable, when it normally would have panicked multiple times (and I’ve been intentionally sleeping it frequently to try to trigger the panic behaviour).


I’m going to go ahead and call this a software issue.


I think the best advice for now is that anyone who can upgrade to Monterey should do that. (And otherwise consider a rollback.)
