STABLE-10 minidump issue on Arndale

[Wojciech Macek]

Hi,

I'm running Arndale (Exynos 5250) system with FreeBSD 10-STABLE. I'd like
to make use of minidumps, so I run the following test:

1. Trigger panic and store a dump
root@:~ # sysctl -w debug.kdb.panic=1
debug.kdb.panic:panic: kdb_sysctl_panic
cpuid = 0
KDB: enter: panic
[ thread pid 650 tid 100086 ]
Stopped at      kdb_enter+0x5c: ldrb    r15, [r15, r15, ror r15]!
db> dump
Physical memory: 2040 MB
Dumping 28 MB: 25 21 17 13 9 5 1
Dump complete
db> reboot�

2. When trying to analyze the dump with kgdb I get an error about unknown
EABI
root@:~ # kgdb kernel.debug /var/crash/vmcore.last

Any hints what I might be doing wrong?

Here is the command I'm using to build world and kernel:
make TARGET_ARCH=armv6 KERNCONF=ARNDALE buildXXXX
