Comment(by lindi):
Here's syslog output I recovered from the SD card. Here's what I remember:
1) I stopped gprs, put phone to hostmode and connected it to nokia
2) I was watching current_now and got really nervous when it showed values
around 2000 mA
3) I disconnected nokia from the phone and was really worried since the
current_now values seemed to stay high
4) I did a few suspend/resume cycles but that did not help, current_now
still showed pretty high values. You can see this if you grep for
'consumption' from the syslog output:
Sep 10 19:11:24 ginger logger: resuming (reason EINT09_PMU:button)
(temperature 31.1) (consumption 19875) (energy 98)
Sep 10 19:19:49 ginger logger: resuming (reason EINT09_PMU:button)
(temperature 31.1) (consumption 18000) (energy 97)
Sep 10 19:38:07 ginger logger: resuming (reason EINT09_PMU:button)
(temperature 30.8) (consumption 13500) (energy 93)
Sep 10 19:55:16 ginger logger: resuming (reason EINT09_PMU:button)
(temperature 55.6) (consumption 1812187) (energy 0)
