I just got a kernel panic on my -current NetBSD/i386 machine at
home ... I mode a crash dump to be analysed a little later, but i
discovered that gdb6 does not handle kcore target anymore.

root@cixy [/var/crash]# gdb /netbsd

(gdb) target kcore netbsd
Undefined target command: "kcore netbsd".  Try "help target".
(gdb) target core netbsd.0.core
"/var/crash/netbsd.0.core" is not a core dump: File format not recognized

Did the kernel core analysis method changed between gdb5 and gdb6 ?

Thanks in advance,
