Well the IDE code hasn't changed a lot recently, so I checked the CVS

Last AIO patch, by Vladimir N. Oleynik.

http://cvs.savannah.nongnu.org/viewvc/qemu/hw/ide.c?root=qemu&r1=1.64&r2=1.65

  

Have we learned something about this issue?  Should I revert the patch
from kvm?  Should qemu?

Sure. The conversion from sync to async mode done in this patch is 
incomplete to say the least.
