(Get the code!)
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.
