Do you have sshfs mounts?
Not sure what sshfs is, in fstab I mount varous remote nfs shares. Also my OS is installed on a M.2 SSD drive and I have another internal SSD drive mounted.

Workaround is to switch to new syntax. fstab manpange mentions how to do that. mount(8) and umount(8) support filesystem subtypes. The subtype is defined by '.subtype' suffix. For example 'fuse.sshfs'. It's recommended to use subtype notation rather than add any prefix to the first fstab field (for example 'sshfs#example.com' is deprecated).

Thank you, that solved it! my fstab file was non-standard, I had omitted the fourth field on my NFS mounts.

I changed: 192.168.1.31:/other /mnt/other nfs to: 192.168.1.31:/other /mnt/other nfs defaults 0 2 The mount worked, it just crashed kpm
