So, it's first successfully found:

and then immediately disconnected:

Makes me wonder if you have some script or daemon killing it, using the
thinkpad_acpi rfkill interface.  This will completely power off the
device, which will look exactly like your log.  Or maybe it's the BIOS
disabling it, since you see the same under Windows?  But then I don't
understand why it is first enabled and then disabled. 

What's the output of 
 cat /sys/devices/platform/thinkpad_acpi/wwan_enable 
?
