Bug#293569: Add megaraid to /etc/mkinitrd/modules doesn't work out
Hi Horms,
Some more background... The machines I'm trying to install the
2.6.8-2-686-smp Debian kernel package are Dell PowerEdge 1850 with a
PERC 4e/Si RAID Controller model with one Hitachi 73,2GB SCSI Ultra320
HotSwap HD factory configured in RAID0.
I have used the sarge_i386_netinst.iso serial 20050127 to install the
machines and the installer 2.6.8 kernel image (linux26 or expert26)
fails to detect the disk (RAID controller) then I've installed the
machine with the kernel 2.4.27 image (linux or expert), this installer
image succeed to detect de RAID controller using the megaraid2 driver
correcting the problem mentioned on
http://lists.debian.org/debian-boot/2004/11/msg00742.html
Then I've choosed to install the 2.6.8-2-i386 kernel image of the
installer and got the 'kernel panic', so I've re-installed the machine
using both kernel 2.4.27 images to detect de RAID to install and the
installation kernel. And finally got the same problem reported by
Robin when trying to install the 2.6.8-2-686-smp kernel image 2.6.8-13
release after the machine was booted with 2.4.27-2-686-smp kernel
image.
I have done the tests you suggested with *no* success, so let's go to
the results and logs:
BEFORE actions:
~# cat /etc/mkinitrd/modules
# /etc/mkinitrd/modules: Kernel modules to load for initrd.
#
# This file should contain the names of kernel modules and their arguments
# (if any) that are needed to mount the root file system, one per line.
# Comments begin with a `#', and everything on the line after them are ignored.
#
# You must run mkinitrd(8) to effect this change.
#
# Examples:
#
# ext2
# wd io=0x300
scsi_mod
megaraid
~#
~# mount /boot/initrd.img-2.6.8-2-686-smp /mnt/ -o ro,loop
~# cat /mnt/loadmodules
modprobe -k scsi_mod
modprobe -k megaraid
modprobe -k vesafb > /dev/null 2>&1
modprobe -k fbcon 2> /dev/null
modprobe -k unix 2> /dev/null
modprobe -k megaraid2
modprobe -k sd_mod
Booted the machine and got the kernel panic.
Then I've decided to do another test adding the sd_mod to put the
modules in the same subset order the mkinitrd do when we don't have
modules in the /etc/mkinitrd/modules file.

Without modules in the /etc/mkinitrd/modules the mkinitrd does, it
seems to do not need scsi_mod:
modprobe -k vesafb > /dev/null 2>&1
modprobe -k fbcon 2> /dev/null
modprobe -k unix 2> /dev/null
modprobe -k megaraid2
modprobe -k sd_mod

Then we've got again the kernel panic.
I have no logs because the kernel doesn't mount anything so I 'hand
paste' what we got from the screen, it is also not possible to page up
the screen because the machine freezes.

Kernel panic: Attempted to kill init!
I've noticed that the screen log is the same in all attempts of
modifying the initrd.
I also try to compile/package (make-kpg) a kernel with the same config
of the Debian kernel package but without initrd and with the necessary
three modules (scsi_mod, megraid, sd_mod) builted in + xfs/ext3/ext2
to see if the kernel 2.6.8 megaraid driver works with RAID controller
PERC 4e/Si. Then let you know.
