Comment(by slm3095om):
I too am suffering from this problem. It started a couple weeks ago. For
testing, I am talking to the modem with cu, here is a log of the
conversation
{{{
AT-Command Interpreter ready
AT+CGMR
+CGMR: "GSM: gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-Moko11"
OK
AT%CSTAT=1;+CMEE=2;+CREG=2
OK
AT+CFUN=1
%CSTAT: PHB, 0
%CSTAT: PHB, 0
%CSTAT: PHB, 0
%CSTAT: PHB, 0
OK
AT+COPS=0,0
OK
+CREG: 2
+CREG: 5,"2710","C60E"
AT-Command Interpreter ready
}}}
I will attach the log file from the modem's debug output.
I do have a spare battery and I have cleaned the contacts. The problem is
present with both batteries. Sorry, but I don't have ready access to a
scope.
One thing that I did notice in my testing is that the modem resets with
2008.12 but it hangs with 2009. I have to do an 'echo 1 > power_on' to get
it back. I thought that was a little odd, I would have expected to at
least have to do 'echo 0 > power_on; echo 1 > power_on'

Comment(by slm3095om):
In the absence of a scope, I ran the following shell script while I reran
my test
{{{
while :
do
ts=`date +%s`
cap=`cat
/sys/devices/platform/bq27000-battery.0/power_supply/bat/capacity`
vol=`cat
/sys/devices/platform/bq27000-battery.0/power_supply/bat/voltage_now`
cur=`cat
/sys/devices/platform/bq27000-battery.0/power_supply/bat/current_now`
echo $ts $cap $vol $cur
usleep 500
done
}}}
If those values are anywhere close to accurate, my battery stays above 4.1
volts the entire time.
