SoftRAID causing kernel panic on Sequoia

Macbook Pro 14 (2021), Sequoia 15.6.1.; SoftRAID 8.6.1.

I have a situation where plugging in my Thunderbolt RAID array causes a kernel panic with SoftRAID.

What can I do to get access back to my softRAID array? Thanks in advance.

I need a SoftRAID support file. 
Try these things:

1. plug in the enclosure 2 minutes or more after startup. Does that let the macOS work without panics? If so, grab a support file.

2. if not, then pull out two of the 4 drives (or 4 of the 8) an inch or so, and connect it, save a support file, then pull the others out, push these in, and save a second support file. 

attach them here.

Here is a Support file to start. I'll try the other actions and see.

This is a start, but I need the support files when only two disks at a time are connected. Thanks!
The panics are indicating a faulty disk. This should not cause a kernel panic, however, so something else is going on, or it is a bug in macOS. Are you able to upgrade to Tahoe? 
If this is pointing to macOS, and we want to submit it as a bug, Apple won't accept it as a bug report unless you are running Tahoe.

(and Tahoe fixed a related kernel panic, perhaps this one also)

I have only 2 drives installed and here is the Support file. However, I'm not sure if this is what you mean?

The hardware is not an OWC enclosure to be clear.

THere are no SoftRAID formatted disks connected in this support file. And I need a support file with two, then the other two, so I can see all the drives.

Also I need either for you to:

upgrade to Tahoe, or get the trial of DriveDx, and install the SMART driver. THen save the support files.
You will know if this is working, by the disk tile in SoftRAID on your USB drives should show SMART results, generally "Passed"

I have installed DriveDX and enabled the extension.

Attached is my support report.

Currently I am able to load the RAID array but it is in 'degraded' mode.

The SMART status on the 5 drives in the Softraid config are all "OK"/green in DriveDX

Glad your drives are OK. Usually when the SMART open source driver is installed, SoftRAID can see the SMART status also. Glad your drives are good. 

Your volume should be rebuilding, unless it is "read only". If you unmount/mount the volume, it just mounts normally?

The rebuild is complete. I've generated a new support file. After this am I all ok now?

@softraid-support so far, yes it mounts and unmounts properly.

Yes you are OK now. Just clear the IO errors from the drives with errors (Utilities menu)

Thank you. One more question. I had one drive drop from the array and had to unmount, re-mount and rebuild. It's working fine again but is that a rare occurrence? Should I be concerned about that? In my other (non SoftRAID) NAS arrays, I rarely have drives drop.
