Well.. order-1 GFP_ATOMIC allocations are unreliable. The networking
code should hanlde the situation and recover. I assume that is
happening in this case?
Perhaps we did something in that code after 2.6.29 which increased the
frequency of the order-1 allocation attempts? Maybe earlier kernels
used order-0 all the time? Those are much more reliable.
