Grub System Panic w/SCSI [SOLVED]

[DagonSphere]

I have an Adaptec AHA2940 SCSI card. Here's my current setup:

sda -- Windows XP & grub in MBR
sdb1 /boot
sdb2 swap
sdb3 /

The kernel starts to boot, but freezes when it tries to mount / with the following error:

VFS: Cannot open root device "sdb3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - Not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Here's my grub.conf
default 0
timeout 10
splashimage=(hd1,0)/grub . . . .

title=Gentoo
root (hd1,0)
kernel /bzImage root=/dev/sdb3

title=Windows XP
rootnoverify (hd0,0)
make active
chainloader +1

fstab is as follows

/dev/sdb1 /boot reiserfs noauto,noatime,notail 1 2
/dev/sdb2 none swap sw 0 0
/dev/sdb3 / reiserfs noatime 0 1
proc /proc proc defaults 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0

Yes, I've compiled resierfs into the kernel, along with emerging reiserfsprogs. It does boot the kernel, so I know that's not the problem

I cannot find my exact SCSI card (Adaptec AHA 2940) in the SCSI drivers section. I forget which one I did add to the kernel, but I'm recompiling it now with AHA152x/2825 -- 1542 -- AACRAID -- -AIC7xxx Fast (and the old also) -- AIC79xx U320 -- I20 RAID, along with some other drivers. I doubt I need the I20 raid, but figured I'd add it in anyways. The Lice CD sees the drive just fine, obviously because I was able to fdisk, mkreiserfs, and install everything. (ALL compiled into the kernel, not as modules)

I've tried changing (hdx,x) in grub to (sdx,x). Even tried changing sdb3 to sda3 with the thought that after it boots the kernel, the drive mappings would get jumbled. Didn't seem logical, but I was willing to try anything.

Thanks for any input!

Additional drivers worked.

Haven't gone back to figure out which one did the trick. If I had to guess, I'd say say it was one of the AHA drivers, maybe the AHA152x/2825 or 1542.
