Hi,

It seems I am more awake today.

A bit of testing using /etc/init.d/boot.localfs
"
lsmod > /root/lsmod.list
"
showed that the megaraid module is loaded with a 2.6.5-7.111-default
kernel, but not with 2.6.5-7.145-default

So:
lsmod > /root/lsmod.list
# Load the megaraid module as kernels more recent than 2.6.5-7.111-default
# do not seem to want to
modprobe -a megaraid
#lsmod > /root/lsmod_after.list

showed the megaraid module being loaded and the file system being
mounted during boot with 2.6.5-7.145-default, from fstab:
/dev/sda1 /raid5 ext3
defaults,usrquota,grpquota 0 2

I did try loading both megaraid and megaraid_mm, but that caused raidmon
to screw up:
lsmod > /root/lsmod.list
# Load the megaraid module as kernels more recent than 2.6.5-7.111-default
# do not seem to want to
modprobe -a megaraid
modprobe -a megaraid_mm
lsmod > /root/lsmod_after.list

as this bit in raidmon did not work:
"
        megadevice="megadev0"
        rm -f /dev/$megadevice 2>/dev/null
        megamajor=`cat /proc/devices|gawk '/megadev/{print$1}' `
        mknod /dev/$megadevice c $megamajor 0 2>/dev/null
"

and this test:
"
        # New check: 10-31-01: Does node exist
        if [ ! -c /dev/$megadevice ]
        then
          echo "
                Character Device Node /dev/$megadevice does not exist.
                Raid Monitor could not be started
                "
          exit 1
        fi
"
failed due to a lack of /dev/megadev0

there seemed to be two entries in /proc/devices matching
'/megadev/{print$1}' so fair enough.

I guess that network card problem could be something similar with kernel
modules. Maybe a simple bit of testing using /etc/init.d/network will find
something??
