    Re: Computer won't boot anymore, /dev/shm and /boot won't mount

    Can you provide the output of:

    Code:
    uname -a
    cat /proc/filesystems
    Do you build your own kernel? Did you modify it? Or install a kernel from a non-standard location?

    No, I'm using the generic kernel from the repositories. I have compiled my own kernel before with the GrSecurity patch before (many weeks before this problem started happening), but the Nvidia driver didn't work so I'm not using that kernel currently, only the default for Ubuntu.

    Long shot, but try this:

    Open /etc/mtab and remove all references to /boot and /dev/shm. Then reboot, the problem should be gone.

    I removed the "discard" option from the entry for /boot in /etc/fstab (I think ext2 doesn't support discard) and it's working now.
