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=3D1 debug.kdb.panic:panic: kdb_sysctl_panic cpuid =3D 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=EF=BF=BD 2. When trying to analyze the dump with kgdb I get an error about unknown EABI root@:~ # kgdb kernel.debug /var/crash/vmcore.last GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
