Now, THIS is a really unexpected message to wake up to…

panic(cpu 2 caller 0xfffffe001db82d44): "physical object not prepared before dirtying: oid 0x74a25b1 flags 0x4040000001 0x1 type 0x4000000b/0x0 xid 0x407f8 0x0 0x407f9 naddr 0x0 0x0\n" @obj.c:4450

…I am sorry? Physical what? Google has nothing on this one.

Macbook Air M1, 8/8/1TB. Monterey 12.3.1 (21E258). Never dirtied on purpose, although I should wipe the screen more often. I just shut the lid for the night, went to sleep, came back to find the laptop restarted itself – the Monterey wallpaper login window was awaiting me. FileVault is on. (I'm questioning the usefulness of FileVault in a computer with storage embedded inside the CPU and impossible to open, but that's another discussion.)

Nothing was connected to USB except the charger.

Has anyone's physical object not been prepared for the dirtying causing a kernel panic?!
 
Looking at
"Kernel Extensions in backtrace:

you can try to disable FileVault and run First Aid on the disk https://support.apple.com/en-us/HT210898

FileVault is off, ran Disk Utility from Recovery, all's good. I'll see if the kernel panic happens again. I had a few earlier random reboots (I blame Monterey) but not because I didn't prepare my object for dirtying.

I'd love to know what that means.
 
Probably APFS related, similar to Microsoft’s “dirty” for NTFS
  • A volume's dirty bit indicates that the file system may be in an inconsistent state. The dirty bit can be set because:
    • The volume is online and it has outstanding changes.
    • Changes were made to the volume and the computer was shut down before the changes were committed to the disk.
    • Corruption was detected on the volume.
  • If the dirty bit is set when the computer restarts, chkdsk runs to verify the file system integrity and to attempt to fix any issues with the volume.

Could be. APFS brought the fragmentation problem, as on NTFS.
