SUMMARY: A1000 & Solaris 9, slow / long boot time

ok, I'll summarize what fixed this problem....

as it turns out, the /kernel/drv/rdnexus.conf file lists 64 different SCSI 
busses to search for when booting, looking for RAID devices... well, there are 
only 3 scsi busses in my machine, so I trimmed the file down to the first 4 scsi 
busses and my boot time was greatly improved....

host% cat /kernel/drv/rdnexus.conf
name="rdnexus" parent="pseudo" instance=0;
name="rdnexus" parent="pseudo" instance=1;
name="rdnexus" parent="pseudo" instance=2;
name="rdnexus" parent="pseudo" instance=3;

#begin commenting....
#name="rdnexus" parent="pseudo" instance=4;
#name="rdnexus" parent="pseudo" instance=5;
#name="rdnexus" parent="pseudo" instance=6;
#.... and so on up to instance=63

To debug what is hanging up your system at boot time, edit the
/etc/system file and put in the following section: (*=comment)

	* Begin Matt's Kernel Module Debug (as directed by sun)
	* to solve the 5 minute timeout at boot problem
	set moddebug=0x80000000 
                          	* End Matts Kernel Module Debug

Thanks for the replies, folks, this is a great list and I appreciate the
feedback on such issues!
