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."
MacBook Pro 13″, macOS 10.14
It might be a hardware issue, but consider the possibility that something installed on the Mac is conflicting with the latest version of the MacOS that is being upgraded to, but worked ok with earlier versions. There are ways to test this, including booting into Safe Mode. A drastic step, maybe not for everyone, but a step I have successfully taken in a case similar to yours, is to make two backups that you have checked are sound. Then erase and reinstall the MacOS, create one generic administrator user (call it "admin") and upgrade to the desired version of the MacOS, but install nothing. You now have a generic, vanilla Mac, much like a brand new unit from the factory. If the problem is present, it is likely to be broken or faulty hardware. If the problem is gone, then migrate users and account and files, but nothing else (no software, no settings), retest for proper behavior, then reinstall software bit by bit, testing after each install to ensure the problem has not returned.
I confess that this seems like strange advice to me when there are a number of users all reporting the same issue immediately following an update? I mean, I guess it can't hurt to be safe, but doesn't it seem more likely there's been a bug introduced in 11.6.4?
I'd been putting off upgrading to Monterey, but currently that seems like the most promising path forward for me.
Thanks for the more informative reply.
I can report no panics so far since Monterey upgrade (despite multiple sleeps where it was likely to panic on 11.6.4). But early days yet; will report back again when it's had more of a chance to panic again.
Out of interest, why would a hardware issue that didn't previously manifest suddenly do so (for multiple users, with the same suspect bundle) following an OS upgrade? Genuinely trying to understand, as this isn't intuitive to me at all.
So this would seem to imply that there may be (is likely to be?) a hardware issue even if an upgrade or roll back resolves the immediate issue (which it so far has for me, though jury is still out.)
So we should still get our hardware checked even so? Are Apple likely to view things this way if we ask them (or just suggest there’s no issue because there’s no immediate symptom)?
Thanks, that's what I'd originally assumed, and makes more sense to me. (I was just a bit confused by previous comments that seemed to imply that it was more likely to be a hardware issue, even if the device was stable on other OS versions.)
The problem definitely still happens in Safe Mode. Also, when I went to the Genius Bar, they were unable to figure out where the problem was, either in software or in hardware. They told me to send in my computer for repair, but I'm not sure that they'll actually accomplish anything because their diagnostics didn't indicate any problems with the component they want to repair.
I tried to update to Monteray but in one night of standby the mac was completely dead. So I went back to Big Sur. I am hoping for a new update that solves these problems that I did not have before 11.6.3. I think I'll be using Spotify instead of Apple Music.
It would definitely be a good idea for Apple to release 11.6.5 to fix this issue, as it isn't exactly a minor inconvenience when your MacBook crashes every time it goes to sleep. They might also manage to do this with an update that isn't 32GB and doesn't take many hours to install. Fingers crossed.
Apple created this issue with 11.6.4 that did not exist until then. I would say that makes it their responsibility to fix it in a more efficient way then to upgrade to a new operating system. Image what would happen if Microsoft had that attitude….
Completely agree. What's also strange is that when I went to the Genius Bar for help, they were unaware of the problem. Does anyone at Apple even read these discussions? Apple created this mess. So why aren't they fixing it? Now. It sounds like upgrading to Monterey isn't easy either. These constant crashes are becoming a major problem for me at work.
Now crashes in Mac OS Big Sur 11.6.4 without any applications started when the computer is put to sleep, not only as I reported earlier when Apple Music is started. Could it be related to the type of Mac? This is a Macbook Air from 2020. My older Macbook works fine with the same system.
I agree; if it's a hardware issue then it's affected a ton of their stock which also isn't great...I myself have experienced this on two different macbooks. Also just FYI I'm having this issue consistently on Monterey so upgrading is unlikely to help.
Not helpful. I followed every step on this page and my computer is still having issues. It's a problem with the update and it needs to be fixed.
Useless. I reported this problem many times, no solution. Apple is cankered.
Sorry mate, no clue how to read panic itself :(
If an upgrade and a rollback both resolve the problem, then I would assume it was something in the update. If the problem still appears after upgrading, I’d assume it is hardware.
Kernel Panic every time I close computer
