Hi,

I've decided to upgrade to kubuntu 9.04(64bit)  from kubuntu 8.10(64bit)
on the following system :

P5N32-E Sli plus motherboard
C2D 6250
4GB of RAM
2x 250GB SATA, RAID1 software for linux (sdc, sdd)
2x150GB Raptor SATA Raid0 for windows (fake raid from motherboard)  (sda, sdb)

I've setup my kubuntu with the alternate CD with a software RAID1).

I run as told the "update-manager -d" command.

Nothing to report on the upgrade (just ask me what to do with the vim
conf file). The system was running well before the upgrade (and as
already been upgraded from 8.04 to 8.10)

On reboot I have this message:

no block devices found (4 times)
Gave up waiting for root device.
ALERT! /dev/md3 does not exist. dropping to a shell!

I've tryed to reboot with the fake raid for windows disabled (as it was
in troubleshouting). no change.

on busybox (which I get after the errors):
in dmesg output I can see these kind of message:  

sdd : sdd1 sdd2 <<6>attept to access beyond end of device
sda: rw=0 want=586067137, limit=293046768
Buffer I/O error on device sda1, logical block 293033536
(but these kind of message appears on gparted livecd)

in ls /dev, I can see the and sdcX sddX partitions are here.

I've no clue on how to bring my system back... (i'm searching)...
