This system 4.0-stable as of last Wednesday with a slightly modified kernel
(RAIDFrame enabled):
[EMAIL PROTECTED]:/home/seklecki# uname -a
OpenBSD br0 4.0 GENERIC+RAIDFrame#2 i386 (full dmesg below)
I will try to recompile Net-SNMP from source to see if the mismatch between
GENERIC and the "recommended" 4.0 binaries is the cause. I will also try to
figure out why it's only partially being built with debugging symbols.
