Surface 3 4G LTE: "critical" events logged for IA7260 Firmware Update

I have a new Surface 3 4G LTE with Windows 10 pre-installed (purchased 28/10/15 from UK Microsoft Store). It appears to be working smoothly, including the mobile broadband, but from day one Event Viewer has been showing a dozen or so DriverFrameworks-UserMode "critical" events per day, both Event ID 10110 "A problem has occurred with one or more user-mode drivers..." and 10111 "The device Surface IA7260 Firmware Update... is offline due to a user-mode driver crash. Windows will attempt to restart the driver 5 more times..." There's also an associated Application Error ID 1000 for faulting WUDFHost.exe (faulting module ntdll.dll). Despite this, the IA7260 Firmware Update appears in Device Manager (as a hidden device) connected and working under the Surface 3 Modem Device . Presumably the driver is eventually starting so all is more or less well, but it is rather alarming to see the log filling with "critical" errors, and of course the Reliability History rating is pretty much rock bottom. The other (likely) side effect is that Update History shows numerous instances of installing "System Firmware Update - ‎18/‎09/‎2015" - supposedly successfully in each case - presumably this update contains the IA7260 firmware update.

Does anyone else see this issue on the 4G LTE model? And/or any suggestions for remedy? Thanks!
