This is likely do to the new default of disabling dma on cdrom drives. This
causes cdrom access to cause insane latency. You can probably found the bug
report I made about this problem if you look into bugzilla. It was marked
NOTABUG. I recommend commenting out the offending lines in /etc/rc.d/rc.sysinit.
Redhat recommends you set dma to 1 using sysctl.

Comment 2 Arjan van de Ven 2002-05-22 14:52:53 UTC

it's easy to check this temporary by typing
hdparm -d 1 /dev/hdc
(assuming hdc is your cdrom)

Does that fix it ?
