Phone keeps on waking up (suspend (wait few seconds or minutes) => wakeup (wait 10s)=> suspend)

[octavsly]

The phone goes to suspend but keeps on waking up every now and then. Can it be because of loosing the GSM signal?

I am using the lastest kernel from ​http://downloads.openmoko.org/releases/Om2008.8-update/

and the latest qtopia*opk from:

Best regards,
Octavian

P.S.
I had the same behavior with a qtopia image.

The output of logread after it woke up would be of interest to me.

[octavsly]

OK. I will try to get one as soon as I see the same behavior.

Did not see this behavior again. It was probably due to poor GSM signal.

Maybe an enhancement can be done:

• many (3) GSM signal loses => disable wake-up, in case of GSM signal loss, for 30min/60min => re-enable wake up at signal loss

Something like some car alarms have when a sensor is activated too many times.

Just had the same behavior. I have increased the log buffer 10 times (/etc/syslog.conf) and I was able to get the log of the resume. Here is the important part (mind the time stamp jump from 9:26 to 9.30:

It appears like it tries to suspend then it wakes up

logread for phone waking up behaviour

[zecke]

According to your log we get +CME ERROR 512 which indicates some sort of modem crash. Please see #1192 and recent versions of Openmoko Qtopia have code to detect that situation and inform the user.
