Plugging iPhone via USB breaks laptop battery recognition/charging
Last modified: 2012-07-02 04:12:57 EDT
Description of problem:
When I plug in my iPhone (to tether to its 3G connection) Fedora stops charging my laptop's battery. If I turn on my laptop with my iPhone already plugged in, the battery is not even recognized and power management settings and other parts of Fedora behave as if I am using a desktop. My laptop is a Lenovo Thinkpad X230.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plug in iPhone for tethering
2. Watch as battery stops charging
3. Reboot with iPhone plugged in to see battery recognition disappear
Battery charges and is recognized normally even with iPhone plugged in.
Battery does not charge if iPhone is plugged in and is not recognized upon reboot if iPhone is still plugged in.
Mixed up 'Actual results' and 'Expected results,' sorry!
When I plug in my iPod touch to my desktop, I get the following in dmesg:
[76869.103686] upowerd: segfault at 0 ip 00000030bc706720 sp 00007fff821229d8 error 4 in libc-2.15.so[30bc600000+1ac000]
The iPod is then not mounted.
This might not be a poweradmin bug.
OK. I've changed this into a upower bug.
In my case, the iPhone is in fact mounted, although I do get these messages in dmesg:
