[Touch-packages] [Bug 1421009] Re: unity8 sometimes hangs on boot
Also reproduced on arale with the branch above after 25 reboots. $ adb shell system-image-cli -i current build number: 22 device name: arale channel: ubuntu-touch/arale-vivid-proposed last update: 2010-01-01 00:29:22 version version: 22 version ubuntu: 30e975dd988b3be7886017b6d46b2821da187d7b8e5e4c7a30b953114b50bb15 version device: 998baf0435d37e42421b39c34a27ed5f872c145f1d2016e08f477d9ad6b8a654 version custom: 76da72854bde96be6e9d546a607550a952b75ca9c3143e0002f457f826056e87 In addition, the first time I ran this test I ended up with a black screen with only the tiny ubuntu logo after two reboots only. Rebooting the phone from the power button was enough to recover it though.
