Re: X1 Yoga 3rd Gen Crash on LTE (Fibocom L850-GL) during high speed download/heavy use

I have recover to RS3(default image of lenovo recovery disk), no problems. After upgrade to RS5 , same issue happen. 

I think it is driver issue or RS5 itself issue. But only Lenovo's Yamato Guys has solution for it. Please fix it.....

Is there an official bug report channel of some sort for issues like this? I doubt a warranty support request will be helpful for this.

Re: X1 Yoga 3rd Gen Crash on LTE (Fibocom L850-GL) during high speed download/heavy use

The crash can be easily reproduced also on Lenovo Thinkpad X1 Carbon 6th gen device (Windows 10, version 1809, 17763.195) when downloading data at relatively high speeds (50-100Mbits/s) over the LTE connection on Fibocom L850-GL. Whenever the crash occurs, a blue screen is generated with the error code PAGE_FAULT_IN_NONPAGED_AREA (NetAdapterCx.sys). After the issue has reproduced, a crash dump appears in C:\Windows\Minidump. WinDbg indicates that the crash may be related to NxGetPacketLayout in NetAdapterCx.

 

FAILURE_ID_HASH_STRING: km:av_r_invalid_netadaptercx!nxgetpacketlayout 

 

NetAdapterCx!NxGetPacketLayout+73 [minio\ndis\cx\xlat\nxpacketlayout.cpp @ 371]

Re: X1 Yoga 3rd Gen Crash on LTE (Fibocom L850-GL) during high speed download/heavy use

I'm also getting almost daily (even multiple times per day) BSOD's when using the Fibocom L850-GL modem on my T480, running the latest drivers from December 11, 2018. 

 

PAGE_FAULT_IN_NONPAGED_AREA, What failed: NetAdapterCx.sys

 

Seems like a general problem with this modem. I've not had good experiences with Lenovo built-in LTE (drivers that crash, failures to connect, and now BSOD's galore!)

I've been experiencing the same problem after updating from 1803 to 1809 on X1 Carbon gen6 with Fibocom. I'm getting sometimes 3 BSODs per day when using LTE connection. No BSODs when I disable cellular connection.

Please Lenovo do something with this driver!

Is Lenovo aware of the BSOD crash issue on Thinkpad laptops related to Fibocom L850-GL LTE modem? It would be greatly appreciated if @Andy_Lenovo would communicate this issue to the relevant Lenovo team. Thanks in advance!
