Public bug reported: Sometime in the past week or so, it seems that unity8 acquired a new bug which causes it to use 100% CPU and stop responding. I saw it happen on krillin rc-proposed 286 and 288 with silo 39 (address-book-app) installed. Jibel saw it with a different silo, and mterry reports seeing it with yet another different silo.
Details are being collected still, but this bug serves as a place to put the data together. For me, the steps involved to trigger it were: 1. Flash rc-proposed to a krillin. 2. Install silo 39, address-book-app, and reboot. (probably not relevant) 3. Log in, configure time zone, disable automatic updates, configure login to use a passcode instead of passphrase, set screen to never turn itself off. 4. Go back to the app scope and launch address-book-app. 5. Tilt the phone to make the screen rotate. At this point, the UI stopped responding and 'top' showed 100% CPU being used by unity8. I tried to get data from gdb, but it wasn't very helpful: (gdb) bt #0 0xa803cce2 in ?? () #1 0xa803cb98 in ?? () Backtrace stopped: previous frame identical to this frame (corrupt stack?) More details are needed. ** Affects: unity8 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1560188 Title: unity8 hang w/ CPU pegged (needs more detail) Status in unity8 package in Ubuntu: New Bug description: Sometime in the past week or so, it seems that unity8 acquired a new bug which causes it to use 100% CPU and stop responding.
