I was able to show how to analyze an oops as follows: prepare an oops in mydriver.ko boot a kernel with debug info. ( prepare it before course ) objdump -Sl mymod.ko | less you will be able to show the exact line of crash. I presented to a few of my colleagues. fast and simple.
analyzing an oops is more than essential. it is a must. Raz On Fri, Jul 10, 2009 at 3:37 AM, Leandro Dorileo<[email protected]> wrote: > Hi Robert > > On Thu, Jul 9, 2009 at 11:19 AM, Robert P. J.
