Hello,

I say every one has a job.

At least it's start up OK, right?

Can you try attached patch? (patch to if_run.c you currently using) Or, here is a patched file
http://gitorious.org/run/run/blobs/raw/cmdq_fix/dev/usb/wlan/if_run.c

I encountered similar problem about 5 days ago. It kind of hard to reproduce. A couple of things have to happen at the right (or wrong) time.

If the modem still hangs at the start up, please let me know. That means the last patch isn't working.
