Description Nadim Kobeissi 2012-06-29 00:10:33 UTC

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):
Fedora 17.


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
  
Actual results:
Battery charges and is recognized normally even with iPhone plugged in.


Expected results:
Battery does not charge if iPhone is plugged in and is not recognized upon reboot if iPhone is still plugged in.

Additional info:
iPhone 4S.

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[21436]: 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:
