Would it be costly to try these different approaches (disable MTP, alternative flash) to help narrow down the root cause? Could we pull out a few devices and let them spin testing these options repeatedly?
When these things do wedge, do we get any debugging information? Note that if we built that headphone cable I mentioned over the weekend, we'd get a serial console. Thanks for summarising the problem and offering some good suggestions for next steps. -- Mailing list: https://launchpad.net/~canonical-ci-engineering Post to : [email protected] Unsubscribe : https://launchpad.net/~canonical-ci-engineering More help : https://help.launchpad.net/ListHelp
