------=_NextPart_001_0000_01C23E06.24DDD980 Content-Type: text/plain; charset="gb2312" Content-Transfer-Encoding: quoted-printable Hi, everybody, I want to debug my kernel based on FreeBSD Current DP-1. I do some steps as the site: http://www.onlamp.com/pub/ct/13 In the kernel conf: options DDB, DDB_UNATTENDED makeoptions DEBUG=3D-g In the /etc/rc.conf: dumpdev=3D"/dev/ad0s1b" =20 dumpdir=3D"/var/crash" =20 savecore_flags=3D"-z" =20 Then, I copy /sys/i386/compile/oyk/kernel.debug /var/crash, and reboot = my box. Now, I debug my kernel, and occur the panic problem. But, I didn't fin= d kernel.0 and vmcore.0 in the /var/crash. And I didn't howto debug the kernel. Thank you!
