State-Changed-Why:
If there's anyone still on the other end of this... is there any reason to
believe this wasn't a driver or hardware issue? The fact that the problem
starts with a driver-level error makes me think it probably isn't LFS.

Reformatting with FFS and no longer seeing the issue doesn't really prove
anything as FFS has much different I/O patterns, and in particular when
rsyncing LFS will be ramming a lot more data down the disk system's throat.
(Or at least, a lot more at once.) If there was a load- or timing-dependent
problem at the disk level it's quite possible that FFS wouldn't trigger it,
especially if you weren't using softupdates.
