not sure what this is, but while at a convention
I was trying to access the internet and(below is
full dmesg) this showed up.

After receiving this, I sat and tried to re-create
my steps to reproduce but had no luck(was even going
todo a bisect n the spot if I could re-create).

OK this stuff is hard to reproduce it seems.. you have an Atheros
AR5418 MAC/BB Rev:2 AR5133 RF Rev:81, what kconfig option do you use
to get the poison stuff? I am just surprised we haven't seen it
ourselves yet. Let me make sure all of us get this kconfig option
enabled.

CONFIG_SLUB_DEBUG and then either CONFIG_SLUB_DEBUG_ON or pass
'slub_debug' as kernel parameter.

Ah OK I had CONFIG_SLUB_DEBUG but not  CONFIG_SLUB_DEBUG_ON, will
enable it from here on.

   Luis


I enable these options as well..
(then see If I can(hopefully)re-create this
then I'll bisect it).
