DSI when in dhclient

[Justin Hibbits]

Something odd I've been running into lately on 32-bit powerpc, when I
run dhclient on an interface, I get a Data Storage Interrupt dropping
me to ddb.  It happens when dhclient is spawning /usr/sbin/arp, and I
don't know why.  I can write directly to the page it's trying to write
into.

Manually setting IP address, everything works (even manually running
arp).

Does anyone else see this?
