To help see if this is an issue in the hv_storvsc driver; I took the storvsc driver code from 3.13.0-34.60 (presumably a good build) and applied it to the 4.2.0-27 kernel (presumably a bad build). Ran tiobench with backups and was able to repro after about 48 hours.

This implies that either:
1) The bad commit is not in the hv_storvsc driver.

2) 3.13.0-34 is not a good build as we previously thought. I'll wait to hear if other people can repro this issue on 3.13.0-34.

The storvsc driver code I took for this snapshot => http://kernel.ubuntu.com/git/ubuntu/ubuntu-trusty.git/tree/drivers/scsi/storvsc_drv.c?id=3402ec8cbd984e8e2a1f99b51ec6a15a23328223
