System: NetBSD 1.6N (BEASTY) #0: Thu Feb  6 10:45:46 CET 2003 martin@beasty.aprisoft.de:/usr/src/sys/arch/i386/compile/BEASTY
Architecture: i386
Machine: i386
>Description:
My i386 SMP machine hangs (deadlock?) reproducably with a -current kernel
as soon as syslogd starts. It does not answer pings.

A kernel from Jan 29 works fine.

Console log:

Adding interface aliases:

wsconscfg: WSMUX_ADD_DEVICE: Device not configured
Starting syslogd.

At this point it hangs. Breaking into ddb:
