Hi,
I am using the Nokia E61 phone on my Fujitsu Siemens Amilo D Celeron
2.8GHz Notebook as an USB-Modem (cdc_acm 2-1:1.10: ttyACM0: USB ACM
device) to connect over UMTS to the internet.
If I plug the USB-cable in the Notebook the system will freeze or I
only get the following message: [ 158.496128] ------------[ cut

A side-effect of this is that I can't shut down the system. It only
works if I let the USB-Cable connected to the pc. If you need more
informations about the problem please ask me.
Thanks

I assume the previous crash was 2.6.19 with SMP? did it work with
earlier kernels?
I have a Nokia E61, I'll try to reproduce it when I'll have a few free
moments.

It happens to me as well, current Fedora 6 update
kernel-2.6.18-1.2849.fc6.i686 UP, with a Nokia E70 in "PC Suite" mode.
It works ok in mass storage mode. Haven't had time to debug this,
though...

What functions does this mode involve?

Something like OBEX-over-USB
