G'day,

When booting a Dell Inspiron 9300 with a NetBSD kernel > 3.99.3 the CDROM/DVD 
drive combo is recognized but fails to operate. A current GENERIC-LAPTOP 
kernel, as of 3-Aug-05, shows the following bootup message:

wd0 at atabus0 drive 0: <HTS548080M9AT00>

Older kernel versions work. Google showed up with several messages describing 
the above problem but didn't reveal any fixes. I've tried several custom 
kernels with and without *FIXUP* options to no avail.

Sysinfo:

Any ideas?
