In trying to create a simple kernel thread that prints out all the =
processes data and stack size, i still get a panic fault (vm_fault on no =
entry) at the printf statement...ive narrowed it down to the ru_idrss =
variable that is causing the problem, im not sure why. I thought maybe I =
was not locking properly or obseriving correct mutexes, but I have tried =
everything. If anyone knows why the fault is occurring at the printf, =
please let me know. =3D)

printf("%d %d\n", (int)p->p_stats->p_ru.ru_isrss, =
