Comment 222 for bug 1470250

@jsalisbury, I moved back to testing only a single machine at a given time,
currently 5e6cf71 is running for ~6 hours, 83215219 is up next

we had 5e6cf71 and 83215219 running at the same time without any issues for 24 hours *but* the problem seems to be easier to reproduce with only one machine running

for the other two builds from #220 I tried to rule out any other potential causes; there was nothing suspicious on the Hyper-V host this time at the time of failure

another thought, did anyone experience the crash with a file system other than ext4?
