Doesn't seem all that similar...
The interesting thing to me is that the 00100104 address is the same in
both crashes, though this one is in a different method.
except for that maybe. But this is LIST_POISON1, and with seemingly
different lists. It may be faster to reproduce if you enable slab/slub
debugging.
Also, this is with power-save NOT disabled (I was hoping to
hit some debugging code I put in for the other crash..hit this instead.)

Looks like a mac80211 bug, but you snipped the stack trace.
I'll apply your deadlock-fix patch, enable slab debugging, and have another go
at it today.
Thanks!
