Hi.

I installed linux-2.5.14 that kernel configuration is as same as linux-2.5.13.
compile is OK, but kernel panic occured at boot up.

You will get more information by showing symbol.
Use ksymoops or do symbolize virtual address by hand (using ``System.map'').
``Call Trace'' may be useful.

I boot up linux-2.5.14 to use vga=771 parameter, Now I boot up linux-2.5.14
to unuse vga parameter, then linux-2.5.14 boot up.

I extracted Call Trace address( nearly ) from /boot/System.map. Is it OK?
