X1 Carbon gen 4 and Sierra Wireless EM7455 WWAN problems after hibernate (Win 7)


I just received my X1 Carbon gen. 4 laptop with a factory installed Sierra Wireless EM7455 WWAN card and provisioned with Windows 7.  Unfortunately, I have a very persistent and annoying problem.


Almost every time it resumes from hibernate mode the WWAN card device fails to restart---the Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A QDLoader Port has an error: "This device cannot start. (code 10)" as reported by the Device Manager.


I have updated the drivers to the latest version  on the support site (version 7.26.4539.0105 of the Sierra Wireless Lenovo Mobile Broadband Driver Package/Device driver version 16.3.1005.41)


Any thoughts?
