Comment 1 for bug 103148

Ok my experience is the similar to above.

It seemed to happen after resizing some fat32 partitions using the gparted livecd and then booting back.

Also before these messages i had the message:

lookup_group: specified group 'nvram' unknown

Which i fixed by adding nvram to the system group or something (I followed instructions from elsewhere on the web).
I can also continue the boot by hitting ctrl-alt-delete at this point and killing this process.
