Bug#278887: initrd-tools: Caused by megaraid2 module using /proc/scsi/megaraid

[Philipp Niemann <debianbugs@azagtoth.de>]

Package: initrd-tools
Version: 0.1.74
Followup-For: Bug #278887

In the script /usr/sbin/mkinitrd, Line 497, is a find which seems to
search /proc/scsi for modules needed to mount the root device. If one
has the megaraid2 module loaded, there will be a directory called
"megaraid" in /proc/scsi.

This seems to have the effect of making /usr/sbin/mkinitrd add
"megaraid" instead of "megaraid2" to initrd/loadmodules, which in turn
renders the system unbootable on DELL PowerEdge * Servers equipped with
the DELL PERC 4e/Si and others (PowerEdge 1850 for my part).

Workaround is to add "megaraid2" on a line by its own to
/etc/mkinitrd/modules and run dpkg-reconfigure kernel-image-<version>
e.g. dpkg-reconfigure kernel-image-2.4.27-1-686-smp

Regards,
Philipp
