Kernel Panic on `zpool import` 2.1.0-rc3, Big Sur 11.5.1
The crash log can be found in the attachments.
After read the following posts,

Here is what I have done to toubleshoot this issue.
1. Stop zpool import -a
2. zpool scrub is completed without any error.
3. Tested with readonly mode. It will not crash.
4. Tested with the following nvram parameters, using 8, 80, 128, 256. It will still crash, if not using readonly mode.
Could you kindly help to share your suggestion on the following?
1. How to troubleshooting this issue?
2. Do you need more information?
As you may see, now I can only have read only access to my home directory (on ZFS). Hope there is a workaround for this issue.
