Sierra Wireless on Rawhide

Hi there,

I've been trying to get UMTS working through the Sierra chip in my
Thinkpad X60s and for some reason, the USB subsystem in F8 TestN and
Rawhide clocks that I have the Sierra chip, configures it (udev
creates /dev/ttyUSB[0-2]) and then immediately disconnects the device,
meaning I no longer see it in lsusb output etc. This was not the case
in F7.

I've tried reverting the Sierra driver to version 1.0.6 (known to work
on RHEL5), to no avail, and I've also tried booting with
usbcore.autosuspend=0 and usbcore.autosuspend=-1. Neither improves the
situation.

In /var/log/messages I get the following snippet around when sierra is
loaded;

Can someone let me know how I can debug this so that this will work in
F8 when it is released?

Thanks!
