I'm playing around with A/UX 3.0.1 on my SE/30, and I'm running into a strange problem where the kernel panics with "!Double Panic: unexpected kernel trap" when there is heavy incoming serial traffic. I've seen this happen both in terminal sessions using
Anybody got any ideas how I can go about diagnosing this? I've made sure that nothing else (i.e. getty instances, appletalk etc.) are using the serial ports, and serial I/O seems to work flawlessly in Mac OS, so I don't think it's a hardware issue.
Presumably the "double panic" message indicates that it paniced while handling a prior panic condition - anyone know how to find out what the underlying panic was?
It's a bit of a frustrating issue to diagnose, since every time it happens, there's a lengthy autorecovery on reboot at best, and manual intervention to repair the filesystem at worst (that's happened a few times now and it's not very fun!).
