We once again have a number of wedged devices:
 ps-maguro-01
 ps-maguro-02
 ps-maguro-03
 ps-mako-01
 ps-mako-03

This has gone beyond the point where it's just an inconvenience. We
have had to disable the maguro testing 3 days in a row, due to loss of
devices.

We have tried a different host and different hubs, neither made a
difference. That leaves either the devices themselves, a problem in
the flash tools or the image itself.

My current (sleep inspired) thoughts on a course of action:
 - Can we engage the foundations team to take a look? Perhaps they can
spot something in our infrastructure or actually find an issue. I know
Sergio has mentioned disabling MTP on the host, but I don't know the
details.
 - Use an alternate flash? Saviq mentioned using "system-image-cli
--build 0 --verbose" to do a light flash. Does anyone know if this is
viable?
 - Throw more devices at the system? Do we have any spare, especially
maguros? I don't want to suggest swapping devices with other those
actively being used for fear of de-stabilizing those tests.
 - Drop the touch device testing? I don't really want to do this, but
if we can't get this stabilized, dealing with the issues may
eventually outweigh the benefits.

What other approaches have I missed?

Thanks,
Francis
