I am trying to find out what the root cause of this error/problem is:
https://bugzilla.redhat.com/show_bug.cgi?id=462425

The problem is that people assume that timeouts with DRDY like that bug 
refers to must be the same problem when it is often not

The first stopping point is to apply the DRQ drain patch I sent to the
list some time ago and is hopefully lined up for 2.6.29. After that point
you can begin to look at the remaining cases, until then its hardly worth
it.

Is it really?  For many SATA controllers, DRQ draining isn't really
necessary.  PATA might be a completely different story tho.
