I test it on my device with my roms, there is a proposed fix, but unfortunately it seems to not always work, e.g. after a very long sleeping/dozing period (and longer uptime, I restart several times a day, when doing tests), the device sometimes still does not wake up.
My alarm clock in the morning sounds heavily distorted in this case and only one cpu is running on 200MHz, sometimes the device wakes up after some seconds, sometimes after 5 minutes (snooze time of my alarm, by the way) it works again. During the day I normally do not see this issue.
It's not easy to find a reproducible way to trigger the issue, so it's not so easy to fix (or to be sure a possible fix really works reliable).
