I've got a Pegasus 2R4 with a volume that is formatted with APFS that is causing continual kernel panics on any system it touches - MacBook Pro 15 through an Apple Thunderbolt 3 to Thunderbolt 2 adapter; a iMac Pro with the same adapter; or the Thunderbolt 2 cable into a MacPro. With every one it takes about 3 - 10 minutes to freeze the machine and when I reboot I see that there's been a kernel panic.
I've scrubbed the MacPro clean to a virigin High Sierra install. I've also tried it with-and-without the Pegasus drivers and firmware is the latest version.
Anyone else experiencing somegthng similar? My whole personal and working life is on those disks and I really need to get access.

Thanks for your response. I'll raise a ticket, however:
1. Using the latest drivers (as I mention in my post)
2. Can't run Mac System Profiler with drive attached as it crashes as soon as the drive mounts.
3. Can't rom Promise Utility report with drive attached as it crashes as soon as the drive mounts.
I've also booted into Online Recovery mode and run Disk Repair on the volume.
