The original error was caused by 3.15, but the error messages were
from 3.14 because that's what Arch install CD uses, and I had to use
the CD because the hosed filesystem was /.
Now that I think about it, setting up another 3.15 installation to try
to recover that FS would be a better idea, but now it's too late.

At any rate, I'm still trying to reproduce this and will surely report
if I succeed. So far, the only thing I've managed to found is that log
record CRC mismatch thing.
