Sorry, I've only been half following along here.... forgive me if someone
mentioned this already.....

IIRC, the some of the DVD drives in E250s were in need of a microcode upgrade.

Try the below link if you have a Toshiba 1401. I think you can determine if you
do by doing:
# iostat -E | grep DVD

The output will look like this:
Vendor: TOSHIBA Product: DVD-ROM SD-M1401 Revision: 1009 Serial No:

This should be public access sunsolve.

There may have been other mfgrs that were in need of an upgrade... YMMV
