my panic_trigger looks like this now: /* int panic_trigger(int *tp) */ ENTRY(panic_trigger) pushl %ebp movl %esp,%ebp xorl %eax, %eax movl $0xdefacedd, %edx lock xchgl %edx, (%edi) cmpl $0, %edx je 0f movl $0, %eax leave ret 0: movl $1, %eax leave ret END(panic_trigger) same result, (actually too same as the address in the stack trace is still the same, is that possible?) cheers --m _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
