This means agressive timeout is not the problem. The problem is the ISR
not being raised at all after sending a read or write request.
If this is the log of the failing case:
https://travis-ci.org/qemu/qemu/builds/35118444
(first time looking at Travis logs, not sure)
The difference between the one failing and the same arch not failing is:
brlapi support yes, linux AIO support yes, uuid support yes, licap-ng
support yes, virtio-blk-data-plane yes, vhdx yes (this configuration
fails).
The difference that is most likely to fail is virtio-blk-data-plane. So
we should start looking there.
Marc
