I am experiencing a similar issue though the system usually lives a few hours. Upgrading from 4.19.0-9 to 4.19.0-10 lead to the system randomly becoming completely unresponsive, with this happening between several minutes until several hours from boot time. Choosing 4.19.0-9 at boot time results in a stable system. Running debian buster with ZFS packages from buster-backports. Please let me know if I can provide additional information.
