error 6 mounting ext3 - kernel panic with 2.6

[Bernie Borenstein]

I have been trying to get 2.6 running on Fedora Core 1
with the new 2.6 kernel.  I've tried DAVEJ, ARJANV and
even built my own kernel.  This machine is an IBM
intellistation with 2 scsi hard drives and a LSI Logic
scsi board.  I've got Redhat 7.3 on the first hard
drive and Fedora Core 1 on the second hard drive. 
I'm booting using GRUB installed in the MBR of drive 1
(the RH7.3 drive).The system does boot correctly with
the latest Fedora Core kernel.  It does seem to be
loading the mptbase and mptscsih drivers.  I did
remake my initrd using mkinitrd.

The error messages are :

Mounting root file system
mount : error 6 mounting ext3
pivotroot : pivot_root (/sysroot, /sysroot/initrd)
failed 2

Here is my modprobe.conf (converted from my modules
conf)

My Grub entry

title=linux-2.6.1-rc2
root (hd1,0) 
kernel /boot/vmlinuz-2.6.1-rc2 root=/dev/sdb1 rhgb
initrd /boot/initrd-2.6.1-rc2

My 2.4 kernel boot lines are set up the same way and
they work.

Any help anyone could provide would be appreciated.
