I took a look and was able to repro on Arale with the latest rc-proposed but it's difficult.
In my instance of the crash, I did not see the PVR kernel logs reported by Simon in comment #7. (Also, I don't see them in the logs attached by Dave and Victor). How were they obtained? >From the logs I obtained, I saw a couple of lines spewed out by the PVR kernel side : ./logs/logs:Mar 17 17:51:36 ubuntu-phablet kernel: [ 688.646227] PVR_K:(Error): 104: RGXGetDeviceHealthStatus: KCCB for DM2 has not progressed (ROFF=10 WOFF=11) [0, ] ./logs/logs:Mar 17 20:55:38 ubuntu-phablet kernel: [ 2670.497641] PVR_K:(Error): 105: RGXGetDeviceHealthStatus: KCCB for DM0 has not progressed (ROFF=1 WOFF=2) [0, ] but not when the crash happened. So I don't think they are related. I did notice a constant stream of the following messages, but they seem to happen even when the camera is seemingly working normally. And sometimes, they don't happen. ... ./logs/logs:Mar 17 21:04:59 ubuntu-phablet kernel: [ 7.331986] [mt-i2c]ERROR,454: id=0,addr: 10, transfer error ./logs/logs:Mar 17 21:04:59 ubuntu-phablet kernel: [ 7.363560] [mt-i2c]ERROR,454: id=0,addr: 10, transfer error ./logs/logs:Mar 17 21:04:59 ubuntu-phablet kernel: [ 7.363701] [mt-i2c]ERROR,454: id=0,addr: 10, transfer error ... I can investigate the GL (PVR) driver side of things more if I someone can tell me how/when PVRSRV related logs appear and how to collect them? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1551811 Title: Opening the camera for the first time leads to reboot Status in camera-app: New Status in Canonical System Image: Confirmed Status in Telegram app: Invalid Status in mir package in Ubuntu: New Bug description: Test case. - Flash the phone. - Open Telegram app. - Fill the account details. - Add a contact (if needed). - Select a contact to send a message. - Tap on the clip to attach a photo. - Select the camera.
