Distribution Version
Linux Kernel
Architecture	AArch64
ZFS Version	2.1.6, the .pkg file for Ventura/AppleSilicon (md5 of disk image download: 6acb8b52c5f383e6ecb9cef0a34ee2cb, from https://openzfsonosx.org/wiki/Downloads#2.1.6)

Describe the problem you're observing

Occasionally, a wild kernel panic appears! Fourth time in as many days, so I'm seeing a pattern now. I would have simply attributed it to the fact that I'm on Sonoma beta 3, but O3X is at the top of the backtrace, so I'm posting this in case it helps. If this is inappropriate at this point in time, I totally understand. This isn't ruining my day, at least not yet!

Describe how to reproduce the problem

Unfortunately, information is thin here. I'm not consciously doing anything I'm aware of in the user space involving ZFS pools. All of the panics have happened while scrolling a website in Safari, with my drive otherwise not being used. My whole OS is running on APFS just as Apple intended; I use ZFS only for my Desktop folder, on a partition on my Mac's internal SSD.

Include any warning/errors/backtraces from the system logs
