Two Bad_Pool_Caller BSOD [USBXHCI.SYS and wdiwifi.sys]

Last time I posted my question, I got those BSOD only when using Blender (when rendering). Now after that, I installed new windows from Microsoft. My PC ran fine for like 2 weeks and today, I again got two new BSOD.

My drivers are all updated. I only get them when I render via Blender. Like, I played Battlefield on ultra for 2-3 hours and no BSOD. I start doing some rendering, and I get BSOD (which are still random. Sometimes the blender finishes rendering, sometimes I get the BSOD)

I am using the latest version of my Wifi Nano USB driver. I did memtest86 and it came out fine. If the cause is still the Wifi lan driver, how can I avoid this? I mean I have the latest driver, how more updated can I be? Windows is also updated. My hardware is same. I didn't connect any external device. I was using the same Nano USB for two weeks and it ran fine with no problem, and now suddenly this problem pops up. I tried some videos on youtube but they are of no help.

It is like the BSOD forgot to come for two weeks, and now it suddenly remembers. I checked system restore, nothing new is installed.

As axe0 wrote, the USB Wifi adapter or its driver should be the culprit

Hi Folktale,

I suggest to remove the Wifi USB adapter to see how it goes.

hey Axe0,

For how long? I mean I was running it for two weeks with no issue. My computer ran for hours with internet connected via that wifi USB adapter. I was also able to do rendering with no crash. These BSODs are weird.

I will try that tomorrow and report it back to you.

Sorry, I don't understand these codes. Are you saying fast boot could be the culprit?

can you help me here a bit? I installed windows 10. Installed driver for graphics(nvidia) and plugged in my wifi USB adapter and windows installed the driver automatically, just like when we plug a USB. Now there is a driver listed on the adapter's manufacturer's and there is a driver from 2016 available to download. Should I go ahead and install that driver?

axe0 said:

You could try to install that driver yes.


The first 2 codes are from dumps.
- First line: the error code your system had including parameters
- "*** WARNING: Unable to verify timestamp for rtwlanu.sys
*** ERROR: Module load completed but symbols could not be loaded for rtwlanu.sys" simply means some files that Windbg (the program we use for analysis) uses are missing. We use this to identify what driver may or may not be involved into the cause excluding Windows drivers.
- The others I don't know for sure, I believe it to be an issue with the new version of Windbg
- Last line says what Windbg thinks the likely cause is, the last driver that was active just before the Windows kernel got active by calling the BSOD event. "USBXHCI!Bulk_Transfer_PrepareForCompletion+134a5" is the function that the driver executed with offset (start position) a memory address + 134a5 added to it.

The next 2 are drivers, both are drivers from Windows.
- driver filename
- driver description
- I think the source?
- how to update them, though since they are Windows drivers they are updated automatically so don't worry about it :)

The last one simply says that there is an issue with fast startup, it may or may not be related to the BSOD so to be safe @zbook suggests to disable fast startup :)

Thank you axe01. But for how long should I unplug the USB to test for BSOD? Since I use my internet via that USB.

Open device manager > expand network adapter > look for any Realtek wirless adapter and uninstall

Code:

RtlWlanu     Realtek Wireless LAN 8 Realtek Wireless LAN 8 Kernel        Manual     Running    OK         TRUE        FALSE        4,096             30,92,480   0          15-11-2016 22:04:02    C:\Windows\system32\drivers\rtwlanu.sys          4,096

Then reinstall the most up to date driver from: Realtek
