Description of problem:
I am unable to boot my system after upgrading kernel to both versions 2.4.9-31
and 2.4.9-34. Kernel is unable to load aic-7xxx module. Thus, root partition is
not mounted and boot process stops dead. I am able to boot kernel 2.4.2-2 with
no problems at all.

There are many other bug reports that appear related to this same issue, not
being able to boot 2.4.9-xx kernels with aic-7xxx module. Most of these are
still open. These newer kernels provide security updates that I'm unable to use.
I have tried creating a new initrd, but this did not help. Is there a solution?

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Upgrade kernel to a 2.4.9-xx version.
2. Verify correct settings in lilo.conf, re-run lilo.
3. Try to re-boot with new kernel. You can't.
	

Actual Results:  Kernel panic and boot process terminates. Leaves an error
message about adding init= line in lilo.conf. This init line is in lilo.conf,
but since no filesystems are mounted, /sbin/init cannot be found.

Expected Results:  System should boot and run.

Additional info:

Something must have changed with the 2.4.9-xx kernels, possibly in the aic-7xxx
module. For example, under /lib/modules/<version>/kernel/drivers/scsi, the size
of my aic-7xxx.o file is 167860 bytes for the 2.4.2-2 kernel, but smaller for
the newer versions: 140052 for the 2.4.9-31, and 140084 bytes for 2.4.9-34.

Some related info from dmesg after booting with the older (working) kernel is
below. On the newer kernels, boot process does not get this far.
