BIG PROBLEM : XFS: Bad magic Number !

[<xfs@xxxxxxxxxxx>]

Hi everybody,

Big problem this morning when I switched on principal PC.
I have :

XFS: bad magic number
XFS: SB validate failed
Kernel Panic: VFS: Unable to mount root fs on 03:04

What can I do ?!!
I really need to save my mailbox on it and some documents I don't backup 
yesterday.

Thank you...Thank you for your help

For information : I use the cvs xfs 2.4.17 with a Debian/Woody update 
yesterday, on a PIII 650 with 256Mo RAM and 30Go HD ATA33

See ya

Lionel
