[Sonoma kernel panic]
Hi, I just got this KP on my very stable OX86 system (GA Designare Z390), running

> zpool version
zfs-macOS-2.1.6-1
zfs-kmod-2.1.6-1

A filemaker database was open, that resides on a zfs volume.

pool: eAtreio
state: ONLINE
scan: scrub repaired 0B in 00:18:29 with 0 errors on Sat Jun 24 10:25:59 2023
config:

This file system has been very stable (on OpenZFS) for years and years.

Hmmm... I think it was related/due to installing OCLP (OpenCore Legacy Patcher). Removed and all is fine --- hope this helps fellow OSX86 users.
