Bug 124273

Description of problem:
I just upgraded from Fedora Core 1 to Fedora Core 2. After the first
reboot, Fedora Core was no longer among the options offered by GRUB!
Booting from the rescue CD and looking at upgrade.log, I saw that the
installation of kernel-2.6.5-1.358.i686.rpm had failed with the
following error:

No module tmscsim found for kernel 2.6.5-1.358, aborting.

With a little help from Google, I found that this was SCSI
controller-related, so I was able to regain my system by removing my
SCSI controller, which was fortunately unused, and reinstalling the
kernel. However, I am sure that this is a showstopper for anyone who
is even more clueless than me, or happen to need their SCSI controller!

Version-Release number of selected component (if applicable):
2.6.5-1.358

How reproducible:
Always.

Steps to Reproduce:
1. Install a DAWICONTROL DC-2974 PCI (or similar, presumably--see
notes) SCSI controller on a system running Fedora Core 1.
2. Upgrade to Fedora Core 2.
  
Actual results:
Mkinitrd fails during the post-install phase with the message
mentioned above, and grub.conf is not updated to boot the new kernel.

Expected results:
Mkinitrd should succeed, and grub.conf should be properly updated.

Additional info:
By editing grub.conf by hand, I was able to boot into the system
without removing the SCSI controller. When I tried to reinstall the
kernel RPM by hand, I got the same error. Ditto for running mkinitrd
by hand. This is why I claim that this is "always" reproducible.

The controller is a DAWICONTROL DC-2974 PCI, which, according to the
manufacturer's web site, uses an AMD AM53C974A chip. 

My computer is a 2GHz Pentium 4.
