Thanks. That makes a big difference to the readability of the traces.

That said, I'm so used to reading even the messy ones that this didn't 
actually tell me anything new (it made it clear that the SCSI error 
handler noise was just noise), but for people who aren't quite as used to 
seeing crap backtraces, your new trace might hopefully put them on the 
right track.

I threw out the parts that didn't look all that relevant, and left the
ata_aux/md0_raid5/hibernate traces here for others to look at without all 
the other noise. Those _seem_ to be the primary suspects in this saga.
