None
>Environment:
Sorry I don't have the ability to submit "uname -a". The Kernel is GENERIC FreeBSD-8.1/i386
>Description:
I have observed this error message on two different computers, Pentium 4 3.4GHz and Pentium 4 3.0Ghz - both dual core chips. They were both Hewlett Packard dc7600 Small Form Factor computers.

The error only occurs when a CD/DVD is in the drive.

The error is:

acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05

I don't know exactly what this error means, but suspect it is an error related to an error in the media/medium, i.e. CD/DVD disc.

I had a different computer (but the same HP dc7600) running FreeBSD-8.0 and this error was not produced.
>How-To-Repeat:
Access the CD/DVD drive with a CD/DVD in it.
