Thanks. It's the return instruction of the EnableInterrupts() function. So a stack overflow in an interrupt handler, which overwrites the return address? The EnableInterrupts() function itself does just 'sti', that'll hardly corrupt anything ... cheers, Gerd ------------------------------------------------------------------------------ _______________________________________________ edk2-devel mailing list edk2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/edk2-devel
