Kernel Panic - Arch Linux [SOLVED] Nothign to see here

Well when loading Arch Linux (0.8 Voodoo Kernel 2.6.19 x86_64) it displays
Code: 
sdb: rw=0, want=144584991, limit=72301727
attempt to acess beyond end of device
About a few hundred times then
Code: 
/init: 1: cannot open /dev/root no such device
Kinit unable to mount root fs on dev(8,21)
init not found
Kernel Panic - not syncing
attempt to kill init
Ive tried commenting out all unnecessary hdd's in /etc/fstab which still ends in a kernel panic. I can mount all the fs under Windows (ext3 IFS) or a Live CD. In which I am assume is some sort of hard drive issue.

Thanks.

Hmm, it looks to me that it has some how screwed up your drive geometry settings and is trying to read an invalid sector. Is this a new kernel you have just tried to install? Try boot into a livecd then fsck that device. Its your root filesystem that is causing the panic looking at that error.

I've been running that specific kernel for a while, so I doubt it's that. Ill try fsck, thanks. Hopefully that will solve the problem.

[EDIT]
Well I'm on with a Ubuntu Live CD. fsck came up with nothign special, BUT I did fdisk -l and it had:

Code: 
Partition 3 does not end on cylinder boundary.

Partition 3 being an extended partition containing the root partition and the home partiton aswell as another.

I should also clarify something:

/dev/sda - Linux HDD (in 3rd SATA)
/dev/sdb,c - Windows HDDs (RAID-0 36GB Raptors, nvraid) (in 1st and 4th SATA)
/dev/sdd - Linux Swap, Files(NTFS), and Programmes (Windows) (in 2nd SATA)
/dev/hda - DVDRW (IDE Primary Master)

Now for some reason when I first installed Arch Linux it had different letters for the hdd's. So what I'm thinking is that its looking for the root partition in a different hdd which would explain why its showing geometry inconsistencies. I have updated /etc/fstab for the changes but, sdb keeps popping up just before Kernel Panic.

Looks fine to me.

Have you changed your hard disks about? I.e changed which ports they are connected too?

Well I did only use to have two hdds. Problem was that when I upgraded I couldn't have it in the order I wanted it. As this didn't work any more;

Code: 
title Windows XP Pro
root (hd2,0)
#savedefault
makeactive
map (hd0)(hd2)
map (hd2)(hd0)
chainloader +1

So I had to change the drive order to accommodate Windows.

/dev/sda - Linux HDD (was in 1st SATA)
/dev/sdb - Windows HDDs (3nd SATA)
/dev/sdc - Linux Swap, Files (in 2nd SATA)

Doesn't really explain why it wants sdb tho. Probably should have mentioned this earlier.
 
Uhm,

kernel /vmlinuz26 root=/dev/sdb5 rw vga=795

You sure that lines right? I was under the impression it should be /dev/sda* from what you have pasted.

Kinit unable to mount root fs on dev(8,21)

Thats a partition on your raid array that its trying to mount as root, shouldn't sda1 or whatever be root? Though I have no clue about raid haha.

That was really stupid... I can't believe I didn't pick that up.
Thanks for pointing it out. :)
