[Wylug-help] RAID woes

[Nik Jewell]

Hi

Solved this now.  The clue was in the missing /etc/modules.conf line -
adding it there is not sufficient - I needed to edit the initrd image as
well to load the megaraid module.  The grsec message (grsecurity kernel
patch) was merely a report, not itself a problem.

Best

Nik
