   you bring up a good point that i forgot to mention. i actually have those
two lines in my /etc/modprobe.conf already. i understand your skepticism about
/sbin/chkconfig kudzu off but there was orginally a bug in kudzu that caused a
kernel panic if kudzu was on with/without the above lines. 

see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=118202

however, i just checked and it seems the kernel panic bug has been fixed...
/sbin/chkconfig kudzu off is no longer necessary. i tested this by booting with
/sbin/chkconfig kudzu on. but seriously, at one time, i could reproduce this
condition every single time with kudzu on (as did others).

   so, i'm going to revise my ealier recommendations about how to get firewire
to work great under FC2 test3:

[root markf78 home]# rpm -q fedora-release initscripts SysVinit kernel kudzu
fedora-release-1.92-1
initscripts-7.50-1
SysVinit-2.85-25
kernel-2.6.3-2.1.253.2.1
kudzu-1.1.58-1

and add the following lines to /etc/modprobe.conf (thanks for the reminder,
should have pointed this out earlier):

alias scsi-hostadapter sbp2
alias ieee1394-controller ohci1394

mark.
