Subject: Re: kern/129508: [panic] Kernel panic with EtherIP (may be related
to SVN commit 178025)

As a workaround, lowering the MTU of the 802.11 interfaces on all of the
access points made the panic go away, until one of the machines that was
panicking was upgraded to 7.2-RELEASE. Afterward, a panic with a
different backtrace started occuring:
