Kernel Panic on Maverick

[gsv666]

Installed Maverick last night... the system has been working fine all day... then on a reboot tonight got the following.

RAMDISK: gzip image found at block 0
usb 1-2: new high speed usb device using ehci_hcd and address 2
uncompression error
VFS: Cannot open root device "mapper/mylaptop-root" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions
0b00 1048575 sr0 driver:sr

Then it gives the Kernel Panic

Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Pid: 1, comm: swapper not tainted 2.6.35-22-generic #35-Ubuntu

Then a call trace...

This is a brand new install of Maverick I copied my files onto a USB and did a fresh install on the whole drive using the alternate CD (the desktop and netbook editions both failed to read on my system)

was previously using Karmic with no issues.

I tried to e2fsck the dev/sda1 from the CD in "repair broken system" mode but the return was "clean" I read that as the file system being intact but this is an area that I have no real knowledge in.

Reinstalled (seemed quicker)
