griggz,

Click my name and private message me the pc service tag number.

Hi Chenks76,

I stepped back to Windows 1809 keeping SA and DELL update. This doesn't change my PC config except OS version. This was the only change when I tried to move to Windows 1903.

Also, I have a version of DELL update outside of SA. If you install only DELL update and not SA, do you also have BSOD ?

@chenks76, Yes, I 100% understand your disappointment!

so an updated support article has been published - https://www.dell.com/support/article/uk/en/ukbsdt1/sln317867/windows-10-resolving-a-bad-pool-caller-bsod-against-the-irst-driver?lang=en

Remove the Intel Rapid Storage Technology Driver (Version 15.44)
Install the latest version of this driver available for your system to resolve the issue:
Go to the Dell Support Site
Enter the service tag or express service code to get drivers specific to how the system shipped
Alternatively, you can choose your system type from the product list to get a general list of drivers for that system
Click on the Drivers and Downloads drawer in the menu
Ensure you have the correct operating system set
Select the Serial ATA drop-down category Look for the Intel Rapid Storage Technology Driver, ensure the version shown is newer than version 15.44
Click on the Download button and follow the onscreen instructions
Restart your system and install the latest version of SupportAssist

this is alll very well and good, however the version that is currently installed IS the latest version of the driver available for my system. so am i supposed to un-install it and then re-install the exact same version?

@DELL-Jesse L please advise as per above

Dell XPS 13-9360 (private data removed)

Same thing on my side: The IRST driver proposed by DELL is the same I already have.

Hi echarlet,

Thanks for posting again.  We've responded that we are currently working with the development teams regarding this issue and will post as soon as more information is available.  Thanks for your patience. 

Are there any updates? I'm posting details since the last reply was in July.

I have an XPS13 9380. I had to re-install windows 10 due to a corrupted driver when I first got my computer. Everything was working fine until I installed Dell SupportAssist. The BSOD with the error Bad_Pool_Caller appeared. I attempted to uninstalled the stupid thing but the BSOD continuously appeared. When it was finally uninstalled Dell SupportAssist I thought all was well based on the forum but my computer crashed 1 minute into restarting. I'm a bit of a computer noob so I didn't know how to run diagnostics and couldn't really do much since every time my computer started it would crash, so I just did a system restore. Not sure if the system is actually fixed since I did this a few hours ago, but at least it didn't crash 1 minute into starting! 

I was experiencing the same BSOD with the error Bad_Pool_Caller after re-install the W10 1903 on my Alienware 17-R5 and use Dell SupportAssist to update the drivers. I have uninstalled the Dell SupportAssist and it's workink fine.

I confirm, this issue still exists. I just made a clean install on Dell XPS 13 (9380), one i install Support Assist it comes to BSOD in less than a minute. I even can not uninstall it in a normal mode, the Windows not survive the first minute after boot up. Not installing SupportAssist results in a stable fast system. I realized less fan activity since the clean install, Dell softwares are really bloat and low quality.

Version 15.xx.xx.xx of IRST is wayyy too old.

Current version is  17.5.2.1024  Date: 8/9/2019

and users of 14 15 16 are advised to update to the current version.

Both Microsoft and Intel have found an incompatibility between the Windows 10 May 2019 Update (build 1903) and certain versions of the Intel RST driver.

The issue still persist. So many re-installs. Finally I got this error message that led me to here. After uninstalling the Dell software everything is back to stable.
