Can't boot after compile kernel-2.6.23.1

[Allen Chen]

Hi, everybody

I have an IBM HS21 blade with LSISAS1064e controller. It works fine with 
RHEL 4 2.6.9-5.ELsmp.
I downloaded linux-2.6.12.6.tar.gz and compiled it. The .config file is 
a copy of /boot/config-2.6.9-5.ELsmp and modified by running make 
xconfig(just add LSISAS1064e support. After I reboot with the new 
kernel, I got this error message at the very beginning of the boot process:
.......

insmod: error inserting "/lib/mptscsih.ko: -1 Unknown symbol in module
insmod: error inserting "/lib/mptsas.ko: -1 Unknown symbol in module
...............

mptsas.ko,mptscsih.ko and sd_mod.ko are created into initrd.img.
I need these modules to boot into LSISAS1064e.

Any help?
Thanks
