I am giving 6.1 a whirl. In the first 5 minutes I have already noticed that
there are some obvious filesystem issues fixed. I ran a tar and compared the
speed to that on one of my 4.x boxes and low and behold they are about the
same. THANK GOD!
Now I didn't put your -j100 to the test but I did give a -j20 a shot. No DMA
issues, no kernel panics, and actually pretty good performance overall.
