Greetings serial wizards; Given the unavailability of the mailing list search engine, I'm wondering if anyone can fill me in on the changes to the sio driver that have been made subsequent to the release of 2.0.5. In particular, I have a system here with an AST 4-port clone that is crashing regularly, usually when modem status changes. I say "a" loosely; the _entire_ system has been changed (except for the case & the modems), and we're at our wit's end as to what to try next. "crash" is loosely defined too - "freeze", "spontaneous reboot" and "trap 12" have all been seen. Normally, I'd suspect hardware in a case like this, and the number of 2.0.5 modem servers around tends to dissuade belief in a serial driver problem, but there's nothing left to suspect 8( If nothing surfaces in the next day or so, we'll be producing a much more detailed report as to what we've tried, but it'd be nice to know what's been changed. (we tried folding the -current sio.c in, but by the time you update everything else, you end up with a nonworking kernel 8( ) -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" -Terry Lambert UNIX: live FreeBSD or die!
