Help: ZFS tasks can not be killed, have to reset computer (USB hardware, drivers fault?)

Happened in earlier kernel and in 5.10.2-2-MANJARO too. Due to maybe USB root hub HW issue or HW HDD issue the ZFS tasks using the external USB HDD hang/freeze and can not be killed using “sudo kill -9 pihere”. Here lsusb|grep hub

There is also issue on ZFS tracker with more details.

Can a developer please take look into that to help discover if Manjaro/kernel can handle this better without need to reset computer once the freeze happen.
