general protection fault on real system

Post by osmosys »

Hi,
I got a general protection fault while testing my os on a real system. The code works fine on both qemu and bochs and shows no errors. Is there any reason why the real system shows fault but not emulator ?

In our os, the general protection fault occurs while killing an application and returning to the shell. For switching of privilege levels, i use a single tss. The single tss is initialized to contains the values of kernel mode esp0 and ss0.

PLEASE HELP US SOON....

Your OS probably relies on memory being zeroed in advance.
