I tried to reproduce this with two MX4: - First one running rc-proposed, the newer kernel with upgraded bluetooth stack and bluez4. - Second one running rc-proposed, the newer kernel with upgraded bluetooth stack and bluez5.
Pat was running the first combination. I saw similar kernel suspend aborts due to the wakeup source MT662x being still active but not such a huge battery drain as Pat had. My battery only lost around 15-20% in ~20h where I just plugged it into my laptop for a few min to fetch a recent syslog in between. The rest of the time the phone was just laying around being paired and connect to a bluetooth device, being connected to a WiFi network and got a GPS fix before I turned the screen off. Statistics look like this: Resume wakeup causes: EINT, 909 100.00% Suspend failure causes: tasks freezer abort 536 99.81% devices failed to suspend 1 0.19% Suspends: 588 suspends aborted (39.28%). 909 suspends succeeded (60.72%). total time: 10361.993895 seconds (87.08%). minimum: 0.400780 seconds. maximum: 74.526359 seconds. mean: 11.399333 seconds. mode: 14.000000 seconds. median: 13.158011 seconds.
