Sun Blade 150 hang on ral0 when configuring

I was using this system as my home router and wireless access point and
 the disk drive died (OpenBSD 4.6).  I set the system aside for a few
months and I
recently took the time and replaced the disk and installed 4.8 with
defaults.  Whenever I mess with
the ral0 interface the box will just hang.  Nothing written to the
console and I have to power cycle to recover.
Very repeatable with a simple ifconfig ral0 down/up.

What is interesting is if I just boot the box and have everything
configured (and not touch ral0), the box
 appears stable.  I did some tests and routed >200 GB through the
wireless and wired network (simultaneously) while
scp files on to the Blade 150 itself on a test network setup and the
box didn't skip a beat.  I go to change the
SSID, wpa passphrase or bring the interface up/down and the box just
locks tight.  This happens
regardless of how long the box has been up.

Any suggestions would be appreciated.

Thanks,
Tony
