I didn't do that, but what I did do was download a nightly build
for Fedora 21, a live CD image, burn it to a disc and boot that.
One would think it has a recent kernel (I neglected to look while
it was running to find out what kernel it was).
so I ran a bunch of commands to copy stuff to and from it, and
while it took a few minutes, it also failed in more or less the same
way. I'd guess that means that whatever the bug is, it's not fixed
in Linux, yet.
