FreeBSD .ucdavis.edu. 5.2-RELEASE FreeBSD 5.2-RELEASE #0: Sun Jan 11 04:21:45 GMT 2004 root at wv1u.btc.adaptec.com:/usr/obj/usr/src/sys/GENERIC i386
Though I indicated I was running 5.2, the problem is with 5.3. I tested it with 5.4-rc1 in hopes it was fixed but it is not. Whenever I boot a FreeBSD version after 5.2, the kernel start up on the CD-ROM installer and on the installed OS (if I go ahead with the install) fails with acd0 errors that READ_BIG timed out. This is an eMachines M2350, with SLIM COMBO drive. The exact same machine works fine on 5.2, so I'm not sure what happened. If I boot into safe mode it works fine, but the CD-ROM drive is very slow -- things install at less than 100 kb/s as opposed to the 700 or 800 kb/s if not running in safe mode.
Merely attempt to install or use FreeBSD 5.3 or 5.4-rc1.
Run in Safe Mode (though this is really undesirable).
