I started seeing this very soon after creating interfaces.

Can you be more specific how one can reproduce?

Enable SLUB debugging, DEBUG_PAGEALLOC (Debug page memory allocations),
lockdep, pre-empt.

OK I just enabled PAGE_ALLOC thingy, it wasn't enabled on my kernel.

Please try creating a bunch of stations on one ath9k phy,

How many?

130 is a nice round number :)

I'll try with a smaller number and see if I can hit it.

Thanks,
Ben
