This amounted to getting 222 MB of of data, compressed with bzip -9 it came to only 18 MB, I've pasted the last 1k lines below but if you want the full log you can grab it here: http://bombadil.infradead.org/~mcgrof/logs/2.6.32-rc6/ath9k-ar9285-2.6.32-rc6-2009-11-11.txt.bz2 Note that both outputs still have the dummy double prints due to some sort of issue I'm having with netconsoel (or the switch or something..)
