[PLUG] redhat v7.o, cd-recorders, and you!

[Erik Yunghans <Erik.Yunghans@bentley.com>]

alright. my first post, and this problem is giving me much mental grief, as
well as being a massive pain in my a$$.
here's the situation:

distro: redhat v7.o (believe me, its almost as bad as you think it is)
kernel: 2.2.17 (with ide-scsi support compiled in)
cdroms: hdb = 6x DVD-ROM Reader
	 hdc = 4x CD-Writer (Matsushita)

problem = 

i can burn a cd fine with my cd-recorder, but i cannot mount any cdroms. no
dice. no nothing. 
here is a sample from my dmesg output >>>
