It looks like the iwi driver allocates DMA memory in iwi_init(), which
is called at runtime. But, by then, memory may be too fragmented to
get a decent DMA memory chunk.
Also, iwi_init() allocates that memory every time, which is a waste.
What it should do, is allocate the DMA memory for the firmware upload
on attach, and just keep it around for reuse whenever the firmware
needs to be loaded.
Reloading the firmware for every init (which is for every interface up/down),
seems heavy-handed.. but I don't know much about this card itself.
