Re: [Crash-utility] crash can't read vmlinux on live system?

Kris Corwin wrote: Hi Kris, First, is the vmlinuz that the kernel is running created from the ./vmlinux file that you're using as an argument? If that's true, then there's no need to use the System.map argument. That's a common misconception, and in fact, when the System.map argument is used, you will end up losing a bit of functionality -- like line-number output from the "dis -l" option. Anyway, I don't think that has anything to do with the problem here. The "x86_omit_frame_pointer" and "xtime" read types are the very first two reads that the crash utility makes from /dev/crash (Red Hat) or from /dev/mem (non-Red Hat). I'm guessing that it continued on and complained about not being able to read the the linux_banner string, and then died? Anyway, could you please post the complete output from "crash -d7 ./vmlinux"? Thanks, Dave
