Subject: BUG: ipheth - NETDEV WATCHDOG: eth1 (ipheth): transmit queue 0
timed out
Hello,
ipheth does not work for me at all with iPhone5 and iOS 6.
Setup:
Thinkpad T60 (32 bit) with openSUSE 12.1 (with current kernel repo)
iPhone5 with iOS 6.1.2
USB-Cable between laptop and iphone
In the moment I enable Hotspot with USB-cable connected to phone and
laptop, I get the following message:

The bug also occurs
- when I turn on hotpot first and plug in the cable afterwards.
- with the vanilla kernel from the same repo (and without loading
the tp_smapi module which taints the kernel in the log above).
- for others (https://bugzilla.novell.com/show_bug.cgi?id=779643).
That link also contains messages from another system with an earlier
kernel other iphone model and earlier iOS.
What other information is required to get this problem resolved?
Thanks
Jörg

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
