 Ok...   Did ZFS with Ubuntu MATE 20.04.    Then installed the Ubuntustudio low latency and control panel. :
 There's a reason why ZFS support is still experimental.
 I'm guessing the lowlatency kernel doesn't have the zfs module
 It does. It's only 4 flags difference.
 Is there a way to get grub to show to see if I can choose other kernel or do the snapshot rollback
 Usually holding shift or esc while booting.
 I didn't have anything on the laptop.   It laterally I clean install
 Troy, you really need to use proper support channels for Ubuntu, this isn't one of them. I mean, if you're testing stuff and finding bugs, awesome, but you really need to use askubuntu.com or #ubuntu on IRC.
