Hi Jack. I discussed this with other kernel engineers this morning and we also felt this was looking more like a FW or hardware issue. I am anxious to hear your results. Thanks for the detailed response.

With kernel 5.8.0.34 it hangs requiring machine reset; no response from mouse or keyboard. No response to ping from a windows machine. All drive activity stops. The hang occurs with the backup drive connected via sata and via usb3 (adapter) The source directories are ext4 (boot drive ssd) and zfs (raidz1 four x 4TB drives). The destination is a single 3TB drive formatted with zfs (drive is about 20% full). The hang occurred about 6 times before I decided to go back to kernel 5.8.0-33 (hangs ocurred with -34). The backup worked fine with kernel -33 (sata and usb3 connect). The install is 20.10. Please let me know if you need more information.
