This isn't something I have the time to work on right now, but I'll give you as many pointers as I can (which isn't much when it comes to kernel debugging) if you want to dig into it.
Thanks!
Scott built this iso for debugging an issue on a Dell 2850 server, but it should work equally well for debugging on anything. Should just be a standard image with the debug tools.
Thanks! Can't find any such debugging tools, though. find / -name ddb find / -name gdb both yield nothing.
As far as how to go about doing this, I recommend: http://www.lemis.com/grog/Papers/Debug-tutorial/
Thanks!
Once you get to the debug prompt, the main thing, I believe, is to run 'bt'
It doesn't seem to break into a debugger when it panics - perhaps debug_on_panic is not set per default on the kernel Scott made. I'm assuming here that one can set BSD sysctl variables to some value when making a kernel, is that right? I've tried poking sequences like \n~# and +++++ onto the serial port, but it never responds with a debugger :-/.. (I hope the debugger is in-kernel, because it never gets as far as initializing the disk, so won't help much if it's userland.) More hints? :) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
