Hi:
I was trying to remember what I did that was odd when this crash occurred then

hit me. You can repeat this panic by doing:
# watch -I -W pts/0
Here is another panic that happened write after issuing "watch" for comparison.

I also need your kernel and debug kernel to fully debug this.
1) Do ssh to machine.
2) watch -i -W pts/0 (does not panic over here)
Can you explain what step 1 is? An scp ?
Refcount is -1.
f_count = 0xffffffff
f_data = 0xfffff800158b0400
In your KGDB, can you enter:
info 0xffffffff81b052d0
Does the attached patch make any difference?
