Not able to load megaraid module after kernel upgrade from 2.4.9-e2 to 2.4.9-e25

["Gonzalo Coello" <gonzalocoello@hotmail.com>]

Hello I am running dell Power Edge 12600, with Firmware 1.68,

I have a Perc 4/Si RAID Controller BIOS version 1.04 FW 2.27 (the last 
version)

I installer Red Hat advanced server 2.4.9-e3 and works fine, the megaraid 
driver is OK, the driver I used is perc-rhas21-1194-a02.tar.gz (the last 
one)

When I upgrade to kernel 2.4.9-e25, using the rpm provided by Red hat, 
happens the same when upgrading to any version, like 2.4.9-e21.

When starting up, the bios can recognize the disk array with no problem, the 
server starts booting OK, but when it gets to load the megaraid module, it 
brakes:

The server is not able to boot any more, here is the error:

----------------

Red Hat nash version 3.2.6 starting
Loading scsi_mod module
SCSI subsystem driver Revision: 1.00

/lib/megaraid.o: init_module:

invalid IO or IRQ parameters

I can clearly see that the driver can't be loaded,there is a problem.

My question is: What is the problem with the driver after upgrading the 
kernel?

I think somehow when red hat is installed with the first kernel, there is 
some aditional configuration with this particular driver that is lost when 
upgrading.

What do I need to reconfigure?

Thanks in advance.
