Problem mounting CD-ROM since 5.2-RELEASE

Wed Jan 14 23:33:41 PST 2004

Hello everyone,
    I recently installed FreeBSD 5.2-RELEASE and can no longer mount my
DVD+RW drive. Everything was working fine under both 5.1-RELEASE and
4.9-STABLE versions of FreeBSD. The symptoms of the problem are as follows:

1) During the boot process, I (sometimes) receive the following kernel
   error message:
   "acd1: FAILURE - READ_BIG status=51<READY,DSC,ERROR> sensekey=ILLEGAL
    REQUEST error=0"

2) When I try to mount the drive, I receive the following:
   "cd9660: /dev/acd1: Input/output error"
   ... and the kernel (sometimes) prints the message appearing above in
   symptom #1.

What I've done:

1) I've tried enabling/disabling DMA for the drive using atacontrol.
2) I cvsup'ed to the latest -CURRENT as of 01/14/04. The problem still
   persists.

What I have:

The DVD+RW drive is connected to a Sil0680 ATA-Medley UDMA133 controller
card. Other information can be found in the attached dmesg output. Any
help or suggestions will (of course!) be greatly appreciated.

Thanks in advance,
Mike
