I've also seen order-0 failures on 2.6.31.5:
Note that this is with a one process hogging and mlocking memory and
min_free_kbytes reduced to 100 to reproduce the problem more easily.
I tried bisecting the issue, but in the end without memory pressure
I can't reproduce it reliably and with the above mentioned pressure
I get allocation failures even on 2.6.30.o
Initially the issue was that the machine hangs after the allocation
failure, but that seems to be a netconsole related issue, since I
didn't get a hang on 2.6.31 compiled without netconsole.
