Comment(by Quozl):

 Still reproduces, on a slightly attenuated 802.11g network, but not on an
 unattenuated network.

 In the ftrace, the flush-d$-range do loop index variable is meant to be a
 virtual address, but is being found set to 7f000000 or other values which
 are more consistent with a physical address in the ''dma-mem-va
 >physical'' range.
