Hi, I made some modifications to the FreeBSD kernel which causes it to crash. I was trying to determine the line number and file of the code that causes the crash using the instructions given at http://www.freebsd.org/handbook/kerneldebug.html I have the following questions related to the above instructions though. I understand we can use dumpon(8) to tell the kernel to dump the core file to a swap partition. If our system is only configured with one swap partition, can we still point the kernel to this partition? I mean would the core file get overwritten when the system reboots and uses the space as swap again. Now, supposedly the kernel is able to write the core file to the swap partition and the system reboots without overwriting the core file, how do we access the core file? Thanks in advance for your help!! Regards, Virdi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
