Yes.

I'm tracking the 4.6 security branch (RELENG_4_6) and I cvsupped and rebuilt
world on July 22nd.

My cdrom drive is a generic 45x cdrom that is detected on boot as:
acd1: CDROM <CD-ROM 45X> at ata1-slave PIO4


I have the following in my /boot/loader.conf (but it didn't seem to change
anything as I got the same errors with our without these items present)
hw.ata.ata_dma="1"
hw.ata.atapi_dma="1"



Trying to mount a cd and then make a cd image by:
mkisofs -o cd.iso /cdrom

gets me the following errors: (and the command never completes)

I can provide more information if you need. Just tell me what else to do.


Mark.
