>Description:
After telnetting into the system this afternoon, I come home to find it had crashed.
This has been pretty consistent, but this is the first time that I have lots
of details. This is a dual pentium 166MMX system on a Tyan Tomcat III motherboard. the
boot messages from the reboot before the crash is attached. I have the debug
kernel and the crash dump if you want it. Ill keep it for a time in case you want it.
Here is the backtrace from the crash dump:
trane# gdb -k /usr/src/sys/compile/TRANE/kernel.debug ./vmcore.0
