Im no expert but it seems that you are missing the aacraid support in your congfig file.
Check by the way a great resouce for linux on dellservers.
Some where in the middle there is information regarding this.
*	aacraid for kernel 2.2.x 
*	aacraid for kernel 2.4.1 to 2.4.17-pre6 
*	aacraid is included in kernels 2.4.17-pre7 already. (enable CONFIG_EXPERIMENTAL=y and CONFIG_SCSI_AACRAID={y,m}) 
*	aacraid for kernels 2.5.x work pending by Alan Cox. (enable CONFIG_EXPERIMENTAL=y and CONFIG_SCSI_AACRAID={y,m}) 

Add this to your config file and recompile.




Hope that helps.

	I have a few  Dell 2650's running linux, we have been running 2.4.28-5
	kernels and they have been relatively stable.  We see some kernel panics
	now and then, but up till now it has been ok.  I need to upgrade the
	kernel on all of our 2650's and 1650's.  I down loaded the vanilla
	2.4.20 kernel, and ran the highmem patch against it since some of our
	machines are running 4GB of memory.  To make a long story short I
	installed the 2.4.20 kernel on 3 2650's running linux software raid and
	they came up just fine and are running ok.  I installed the kernel on 1
	of my 2650's with PERC3di cards in them, and now I get the message in
	the subject line. The lines about the error start with
	kmod: failed to exec /sbin/modprobe -s -k block-major-8, errno=2
	VFS: Cannoto open root device "sda1" or 08:01
	please append a correct "root=" boot option
	Redhat 7.3
	Dell Poweredge 2650
	PERC3 di
	4x36 internal disks in a raid 5 container
	Attached is the .config file for my 2.4.20 kernel
	Any help would be appreciated.
