I just had to do a clean, and I have the mq kernel options I mentioned in my
previous mail enabled. (mq should be disabled) and it appears to still be
causing issues. current io scheduler appears to be cfq, and it took that "make
clean" about 4 minutes, a lot of that time was spent with plasma, intelij, and
chrome all starved of IO.
I did switch to a terminal and checked iostat -d 1, and it showed very little
actual io for the time I was looking at it.
I have no idea what's going on.
