Keywords: Modules Ooops CD-ROM DVD

Hi,

Currently running Redhat 7.2 (uname = 'Linux corona 2.4.7-10 #1 Thu Sep
6 16:46:36 EDT 2001 i686 unknown'). AMD 1600, Asus AV333 Motherboard,
MATSHITADVD-ROM SR-8587, ATAPI CD/DVD-ROM drive.  I get the following
Ooops on booting (output below).  The CD-Rom will become unusable and
the ide-cd module will remain in the initalising state (judging by the
output from lsmod).  It occurs intermittantly, a reboot has so far fixed
the problem.  It has occured twice in the last 6 or so boots of my
machine.  If you need any more info let me know.  I am not on the lkml
so if you could cc me in the reply that would be appreciated.

Thanks,
Michael Barker
