Comment 231 for bug 1470250

@jsalisbury:
As an update to my latest post:
I re-ran a few even older builds on the weekend:
adbb4e646 - good after 40hours (bad before, might have been another victim of the disk filling up, I think I might have screwed up this run too)
da1674843 - bad after 8 hours (consistent with previous tests)
4c48c359b - currently running, but seems good so far (16hours+, would be consistent with your result)

So, the 4c48c359b..da1674843 range seems plausible. From this range one commit is sticking out which seems related to our problem:

d215f91 scsi: handle flush errors properly
This adds/changes error handling for SCSI non-block commands; as a guess this might either be overzealous in handling an error from hv or the error just silently happened but was ignored?
