There are several threads that show similar problems with acd, and there is a PR i386/37420: Copying large files from an IDE CD-ROM to a harddrive causes a system lock-up. Some have had success by using atacontrol to change drive to dma mode. This only reduces the frequency of the problem in my case. --- Christopher Hall <[EMAIL PROTECTED]> Fax: +886-2-2795-3030 Christopher Hall <[EMAIL PROTECTED]> Phone: +886-2-2795-5799 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
