T480 hibernation breaks WWAN L850-GL

Hi!

 

I have a new T480 with the factory installed WWAN option. It works on a fresh startup, but when the laptop goes into hibernate mode (not sleep) and then I wake it up, the WWAN stops workding. Windows Device Manager shows it as "Windows has stopped this device because it has reported problems. (Code 43)"

 

Why does this factory installed option not work correctly in normal use? I would prefer not to have to disable hibernate or have to restart the laptop every time I want to have working WWAN.

 

Thanks for any advice!

Just updating here that the latest set of BIOS patches and L850-GL drivers seems to have addressed this issue.
