Fedora kernel list - Aug 2007 - how to debug my kernel

Hi,

 I''m currently working on a project which needs to modify linux
scheduler.
But my new kernel always gets crashed after one-day''s run. There is no
OOPS
message coming out when it crashed.
 What should I do?

Best regards
Feng

Post a pointer to your code to Linux kernel and ask there?
Seriously, how do you hope us to guess what''s wrong with no information
at all ?

The most simple solution may be to use serial console :-).
You need a dummy (with cross TX/RX) serial cable connecting the box with
your modified kernel as the ''debug end'' and another
Windows/Linux box as
''console''.
Boot your kernel with parameter "console=ttyS0,115200" (or any speed
your
console support), and set your console properly ("remote terminal" on
Windows or minicom on Linux), then you can see the kernel output on your
console.
Set the screen buffer of your console as big as you wish. :-)
