Heh, the devel version of sym2 (that isn't submitted yet because
it depends on a few changes to the SPI transport that James hasn't
integrated yet) would probably fix this as it doesn't call iounmap()
until the driver exits.

"Next the statesmen will invent cheap lies, putting the blame upon
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
