movl, but it's not its ofwn fault. My guess is that right after sti, an interrupt is triggered while nop is being executed, gets handled after nop is executed, and we return to movl, but somehow the return doesn't reactivate the kernel pagetable or privilege. Looking at the registers you have again, I see cs 0x8 ds 0x10 These are correct. So that must the the pagetable that is incorrect. Check out cr3 and such. Samuel
