Hi,
Everytime I get a panic on Sheevaplug dumping the kernel core fails. Is
this a know issue?
[root@sheeva ~]# uname -a
FreeBSD sheeva.klop.ws 11.0-CURRENT FreeBSD 11.0-CURRENT #6 r283161M: Thu

root@sjakie.klop.ws:/usr/obj-arm/arm.arm/usr/src-arm/sys/SHEEVAPLUG arm
I run on usb-stick with a dedicated swap slice/partition. Isn't it
possible to use this as swap? I have dumpdev="AUTO" in rc.conf.
[root@sheeva ~]# gpart show

Below is the stack after calling dump. Unfortunately I don't have the
original panic.
Regards,
Ronald.
