Anything prior to 10.43 doesn't appear to have BSOD issue.

Re:rtump64x64.sys bluescreen on X1 Yoga Gen 4 attached to ThinkPad Thunderbolt 3 Dock - Type 40AC

I'm not entirely sure about that last statement from Brian. In some of my testing I was using laptops on 10.39 drivers and still getting problems (This was a T15 laptop on an ThinkPad USB-C Dock Gen 2 (Type 40AS). So I'd add that you should perhaps go back to drivers previous to that and see how it goes - and let us know how it works out!

 

Thanks.

Just to let everyone know. My boss escalated a ticket I'd created with Lenovo support through CDW where the company buys all our Lenovo gear. CDW relayed a the following response back from Lenovo:

 

"This sounds like an issue with the client's software. If the client is running a custom image, it is likely the issue might be brought on by something on the customer's configuration, that is throwing this off..

Even if that is not the case, since the network is reported to only drop when using ZOOM and MS Teams, aside from updating all of the drivers, firmware, BIOS, and recommending updating the OS, the support center is pretty limited on what they can do to help with this one. "

 

My boss was a little shocked at how little they seemed to know about this issue, and his response was to send back forum links to this thread and others, and to see if a meeting could be setup with CDW and a Lenovo rep. to discuss how they are going to take the problem seriously or our company is going to start buying its equipment from another manufacturer.

 

Now I don't know where Realtek is on this issue. If they previously had released a test driver to try and fix the problem, then they are at least aware of it. But clearly Lenovo hasn't been taking this issue seriously or applying any pressure on Realtek to quickly resolve it.

 

Considering that in these current times, about 80% of my company's business is being conducted remotely, getting a reply that is basically "Sorry, we can't help" doesn't cut it. At least they could be reviewing those older drivers that people have reported resolves the problem and determining if those are still safe to use, or if there could be unresolved security issues missing from them.

 

I'll update more when the results of my Lenovo ticket escalation is reported back by next Monday. In the meantime, I suggest everyone open a support ticket on this issue if they haven't already, and start making some noise, or we may never get this issue fixed.

As the person who started this thread two months ago I can assure you that Lenovo is very aware of this issue. I know this due to contact I have had with them. I am also sure Realtek is aware as I have submitted memory.dmp files to them to analyze and attempt to determine cause. I have further engaged Microsoft resources as much I can to also investigate this issue. This issue is primarily with Lenovo USB-C and Thunderbolt 3 docks and USB Ethernet dongles. This is a subset of the larger Lenovo install base of devices.

 

I am just as frustrated as you at the length of time it has taken. Unfortunately Lenovo doesn't build drivers for this device Realtek does. Lenovo isn't pushing the driver to your machine Microsoft is. However we all bought the equipment from Lenovo so that is who we can talk to.

Thanks for the information Brian. It helps - a little. lol. I've been guilty of skipping some of the forum content and not going all the way back to the beginning of the thread. So hearing about the actions that others have taken on this issue really does help.

 

Intermittent bugs are the worst. And the fact that I can run a Zoom call for 2 to 3 minutes perfectly fine before it crashes, suggests the bug is deep. I'd even suggest that perhaps the chip is becoming under-powered or getting hot when under heavy use - BUT if there are drivers from 2019 that fix the issue, then maybe not. Unless perhaps there are more features on that chip that are now in use with the latest drivers - and hence generating more heat. If it is a heat or power issue then its LENOVO's engineers that need to be looking at this and perhaps start designing their Docks with a fan or better power managment. Didn't someone post that they were trying to resolve the issue by switching to a larger power supply? I'll look around for that info.

 

Thanks Brian.

I have not seen a response from a Lenovo employee on this forum in a while. Can we confirm that Lenovo is still actively working on this issue with Realtek? Currently, my customer has to remove the ethernet adapter from their dock and plug it and the dock directly into her computer to avoid the Realtek driver issue.

I have roughly thirty Gen1 Thunderbolt 3 docks and about the same number of Gen 2 Thunderbolt 3 docks. They are connected to various generations and models of Lenovo ThinkPads, i.e. X1 Carbons, T580s, P15s. All docks are connected to the appropriate a/c power adapters. A number of docking stations had firmware updates applied (v10023 for the Gen 1s and v3.1.68 for the Gen 2s). All machines are running Realtek driver version 10.44.1214.2020. A problem was first reported to our help desk on 2/16/2021 (note: Microsoft Patch Tuesday was 2/9/2021). The symptoms indicated an intermittent, momentary drop in the network connection. Over the following week the number of similar reports had grown to roughly 20 affected users. The symptom was the same for all users, two of our internal, LAN based applications, would simultaneously report a network error.  For some users it would occur once or twice a day, while others had it every 10 to 15 minutes. Outlook seemed unaffected, web based applications seemed unaffected. To date, only about 20 of the 60 docks are presenting the problem. All of our internal testing has lead us to this: In all cases, moving the Ethernet connection to an alternate Ethernet adapter, NOT based on the Realtek chipset, corrected the problem.

 

We really hope that Lenovo is working with Realtek and/or Microsoft to resolve this apparent driver issue.

Has anyone tried this driver that Realtek released last week?

We have received an updated driver from Realtek which we have tested with a few customers who have not seen the BSOD issue so far.  I've made the new driver available here until it can be published to our support site:

https://download.lenovo.com/cdrt/eval/Install_USB_AllInOne_KeepNewDriver_10045_8060_7053.sfx.exe

 

Please try this driver and let us know if any issue.

That is the PCIe driver vs. the USB driver Realtek USB FE / GBE / 2.5G / Gaming Ethernet Family Controller Software - REALTEK. Hopefully Lenovo will have something to share soon.
