Well, this only tells you that an attempt to make order 5 allocation failed,
which is not unusual at all.

Allocations of this order are quite likely to fail if memory is fragmented,
the probability of which rises with the number of suspend-resume cycles already
carried out.

I guess the driver releases its DMA buffer during suspend and attempts to
allocate it back on resume, which is not really smart (if that really is the
case).

Thanks,
Rafael
