It negotiates ultra speeds, but it causes much grief when there is much activity on the bus. The symptoms I noticed started with the kernel refusing to communicate with anything in /dev (I usually run X, which continued to work... at least long enough to see what was happening), followed by an optional spew of many messages something like 'ncr: device timed out...' in xconsole. At this point, opening windows for programs already in the cache that also don't use anything from /dev still worked. As soon as I touched anything that also touched the disk or anything in /dev, the machine completely locked up. Moving said Micropolis disk to a fast-scsi controller fixed the problem. -- Zach Heilig -- zach@gaffaneys.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
