Doesn't seem like this is > the problem (?) The problem is that a number of video cards (many S3-based, for starters) occupy the same port addresses as the fourth serial port. In order to successfully probe the second serial port in a four port system, it is necessary to write to the fourth port, which can upset some video adapters, possibly causing the system to crash. > A technician at Swedish ICL has exactly the same symptoms.

If it was a commercial system, they'd be sitting still twiddling their thumbs waiting for a patch. There are plenty of people who'd be more than happy to help them out fixing either their hardware or FreeBSD 8( > Peter Olsson Email: pol@leissner.se -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 041-122-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] "Who does BSD?"
