I hope you're aware that alt-sysrq-t has been broken for some time?

include/linux/sched.h:

#define TASK_RUNNING 0
#define TASK_INTERRUPTIBLE 1
#define TASK_UNINTERRUPTIBLE 2
#define TASK_STOPPED 4
#define TASK_ZOMBIE 8
#define TASK_DEAD 16

kernel/sched.c:

static const char * stat_nam[] = { "R", "S", "D", "Z", "T", "W" };

fs/proc/array.c:

static const char *task_state_array[] = {
"R (running)", /* 0 */
"S (sleeping)", /* 1 */
"D (disk sleep)", /* 2 */
"T (stopped)", /* 8 */
"Z (zombie)", /* 4 */
"X (dead)" /* 16 */
};

So, for one more time, here's another mailing of the same patch to fix
this brokenness. In addition, we fix the wrong comment in fs/proc/array.c
