Coincident with 11.5.2 update started getting system crashes with message:
panic(cpu 3 caller 0xfffffe001a3cb344): "busy timeout[0], (60s): 'AppleAPFSMedia'"
Reloaded Mac OS X and ran disk utility on disk (no errors found).
Anyone else seeing this?
Have an M1 13in MacBook pro
MacBook Pro 13″, macOS 11.4
In general, a kernel panic will not be caused by disk errors. Kernel panics are primarily caused by third-party kernel extensions and hardware faults.
Look in the panic log for the loaded kexts. If there are any not made by Apple, they could be the cause. You can post the full log in the Additional Text area (document icon in toolbar).

My main board replaced by Apple and problem resolved
Nothing more in that log to implicate anything but hardware.
Since it seems to be a problem with the file system, maybe erase and reinstall, then migrate from your backup.
Maybe just reinstalling the OS might help.

Hello wejnyc!
Looks like you are having issues with your Mac crashing after updating. We want to help! Is the device fully restarting when the crashes occur? If so, this article has some great steps to start with: If your Mac restarts and a message appears.
Cheers!
I had this problem and sought support from Apple. The system has been re-installed.
Since then, I no longer have this problem.
I have the same issue with my M1 13in MacBook pro. After updating to Big Sur 11.5.2, the machine is crashing several times per day.
Error log:
panic(cpu 1 caller 0xfffffe002b50f344): "busy timeout[0], (60s): 'AppleAPFSMedia'"
Strangely with no changes on my side, my system has stopped crashing. Don't know why or how. I was getting 3 to 5 crashes per day. Nothing I did (reload OS X, ran first aid on disk) worked. Booting in safe mode, it still crashed.
Maybe an auto update fixed something? I have no clue but will continue to monitor.
I know it's frustrating.
My problem vanished by itself In roughly 2or3 weeks, with no changes on my part. I have no explanation.
I tried safe boot but it still failed with that.
Was close to returning to Apple for repair and suddenly it stopped.
Good luck
This happens to me with Big Sur 11.6 too, on an iMac M1. All kexts are Apple, there is not a single 3rd party extension loaded.
The panic message is systematically something like
panic(cpu 0 caller 0xfffffe00191a3338): "busy timeout[0], (60s): 'AppleAPFSMedia'"
The crashes happen daily and this has been going on for a month.
This is becoming annoying.
Posting full trouble report if anyone can make sense as to what is implicated.
Crashes continued after booting in safe mode, and reinstalling OS. Ran first aid on Fisk and this checked out.
Me too ! boring
