Public bug reported:
I'm using rsync to backup directories. 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.
