Evertyime I boot up I gett a long string of weird buffer errors shortly
after udev starts up;
stuff like

nbd0: Request when not-ready
end_request: I/O error, dev nbd0, sector 4294965120

where ndb0 changes up to ndb12.

I still have no clue what dev/ndb0 refers to, but the computer still seems
to be running fine.
fsck'ing the drives revealed nothing and I might run a memory test later on.
(some part of me fears it's my ram, tho, which sounds like it'd make sense.
)


Any ideas?
