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@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.
