The idea I was toying with is that previous filesystem activity (making
the temp install, the server's never-fsync'd writes, etc) has built up a

writing all that data. So the issues we're seeing would come and go
depending on the timing of that I/O spike. I'm not sure how to prove
such a theory from here.
Yeah. It's faintly possible that a kernel upgrade will help.
Another data point. I have another RPi2B that is running Debian Wheezy
rather than the Fedora remix. I'm running the same test on it we ran
yesterday on axolotl. It seems to be running without having the same
problems. So maybe the particular kernel port to ARM is what's tripping
