Marc, nexus-5-kot49h-1 became wedged a bit ago. It wouldn't reboot via adb although I was able to get a shell on the device. Rebooting the host resulted in it being listed under devices as unknown. When you check on the other nexus 5 devices in bug 1160499 can you reboot nexus-5-kot49h-1 again? If it fails like this again, I will recommend that we remove it and recyle it. Thanks.
The device was hung up. Marc rebooted and it is showing up in devices ok. I'll put it back into rotation during the next reboot or when we catch up on builds. Thanks Marc!
