Bug#548290: 2.6.30 cannot find root file system

[Mark Niven <mniven@trendline.co.il>]

I had the same problem with the 2.6.30 kernel. It seems to me that this kernel 
has a problem recognising UUID designations: booting into the previous 2.6.29 
worked fine. I then edited the linux command line from within the grub shell 
at boot time, replacing root=UUID=........ to a straightforward 
root=/dev/hdax, which also worked fine. I then reran update-grub which 
replaced the UUID entries within grub.cfg with /dev/hdax and since then I have 
no problems.
