Alignment Fault 1 on SHEEVAPLUG

[Ronald Klop]

Hi,

Running portmaster on an nfs mounted /usr/ports I got the panic below.

FreeBSD 11.0-CURRENT #5 r272028M: Mon Oct 20 18:33:43 CEST 2014
     root at sjakie.klop.ws:/usr/obj-arm/arm.arm/usr/src-arm/sys/SHEEVAPLUG arm

I attached the diff of my kernel config/src tree.

It is still in the debugger. If I can send more information please tell me.

Regards,
Ronald.
