I've boostrapped 3 machines, identical Hardware, with Netinstall and installed "ubuntu-desktop" and "xubuntu-desktop" packages afterwards.

Every time the boot, I get the message
"""the disk drive for /tmp is not ready or not yet present

Continue to wait; or press S to skip or M for manual recovery"""

Sometimes it disappears after a ~3 seconds but sometimes it takes 1min < time < 2min to continue booting.

When I press "M" I'm prompted for the root password. I could now cd to "/tmp". When I do "ls" now it spills my terminal full with aprox. thousands of entries constisting of aprox. 10 alphanumeric (or hex, dunno) characters. During the list it regularly hangs for a second or two.

After a short time, when I do "ls" again, I see an empty directory.

When I press "S" instead the system continues to boot and I'm able to login to the console and can see the same issues with files misteriously appearing and vanishing.

When the time's up and the files are gone, I could login to desktop just fine, but while files are there I get errors originating on not being able to create tempfiles in "/tmp".

My Root-FS is ext4 on LVM and I don't have anything mounted on "/tmp". "/tmp" is a plain directory residing on "/".

I have absolutely no clue what's wrong there. I couldn't find posts about that problem in google or on this forum.

If there are any additional Info's i could provide to help hunting down this problem please let me know.

Do you have any recommendations for me?

I tried to rebootstrap the boxes but this didn't make any difference.

I don't know if it's relevant but I use SSD-Disks in the machines.
