Thanks for any help ~ Chris I'm also new to this so take it with a grain of salt. You'll need kernel with debug symbols (kernel.debug). Add this line to your kernel config (it is included in 6.2 GENERIC): makeoptions DEBUG=-g# Build kernel with gdb(1) debug symbols The 'new make procedure' will produce both kernel and kernel.debug files in obj/usr/src/sys/YOUR_KERNEL_NAME Sounds good, Karol. Will my current core file work with the recompiled kernel? Or will I have to generate a new one? I've got no idea, cc'ing @freebsd-questions, someone here may have one.

Re: obtaining kernel.debug
I'm trying to debug some panics on my system, and the section in the handbook that goes over kernel debugging points to /usr/obj/usr/src/sys/KERNEL as the location of kernel.debug. But I don't have this file there. I only have 'kernel'. Just in case this was not obvious, KERNEL there is meta-linguistic. Yours might be in GENERIC, MYKERNEL, etc. -- the same place where you built the currently-running kernel. If you're running the original CD-installed kernel, I suppose the corresponding place would be GENERIC (but I don't know offhand whether the standard install includes GENERIC/kernel.debug -- if not, perhaps it should). Can I just use the 'kernel' file, or is there a difference between 'kernel' and 'kernel.debug'? The code and data are the same, but 'kernel.debug' also contains debugging records (symbols, source line references, etc). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
