Description Juergen Weigert 2011-05-29 14:14:38 UTC

I am using a Nokia E71i for tethering with my lenovo x60s.

When connecting the phone via usb cable, the following messages appears in dmesg:

This is fixed with 2.6.37.6, right?

It failed to connect today. Probably related to that oops above. I tried 
rmmod cdc_phonet
rmmod phonet
and reconnecting the USB cable. Same oops. After a reboot, and 3 or 4 attempts I got a working connection, despite the oops.

Yeah, my bad, sorry. The fix went in a bit later even after 37.6 was released. It will be in the next kernel update. You can check with daily snapshot from:
