Not doing snapshots. Did a reboot with the options to upgrade to v2 -- it failed, in that the disk check took more than 6 minutes, but it worked, and the second time I was able to boot, and -- knock on wood -- so far it has not hung. I wonder why they put 5.3.0 as the standard advanced Kernel in Ubuntu LTS if it has a data corruption bug. I don't know if I've seen any release of 5.4.14 in a PPA yet -- manual kernel install is such a pain the few times I have done it. I could revert, but the reason I switched to 5.3, not long ago, was another problem with sound drivers. BTW, even though it now works, it still takes 90 seconds every boot doing a disk check, even after what I think is a clean shutdown. I presume that is not normal, any clues on what may cause that?
