[Nexus 4 Q&A, Help & Troubleshooting] f5wA9RBE:
Hi, I've been having issues with the suspend_backoff kernel wakelock since installing CM 10.1.3 stable. It is a fresh install (performed reset in CWM) with almost no user apps. I have disabled and signed out of most Google services, e.g. Google+, Hangouts, Google apps location, Google search, tailored ads, app verification. Bluetooth, NFC, and GPS are all disabled.

When Wi-Fi is enabled, I seem to get "no data connection". The phone is being kept awake by suspend_backoff.

When Wi-Fi is disabled and I am connected to 3G, this problem disappears and the phone is able to enter deep sleep.

I've tried to search for a solution. It is unrelated to the old msm_hsic_host wakelock problem that was fixed upstream by Google. It is also unrelated to Google Chrome problem, as it is not installed. I have tried deleting data and cache for Google apps and services, which does not appear to fix the issue.
