Seen in my dmesg - it's had the 'Firmware Bug' message for roughly forever, but apparently somewhere recently a warning crawled in. 2.6.38-rc5-next-20110222 did not throw the warning, jsut the firmware bug msg. Hope somebody recognizes it, I won't be able to bisect this one for a bit (I have 2 or 3 other things I have a bigger need to track down).
