UNSOLVED
XPS 8940, NEW BIOS, V2.11.0 out today.
OK, just noticed this.
However under Addition Details, Important Information I see this:
===============
- Once the BIOS is upgraded, you cannot downgrade the BIOS to versions earlier than 2.11.0. BIOS downgrades are restricted when there are security updates and important fixes with earlier versions that impact the functionality of the system.
===============
It doesn't seem to be a major change, but WHY can't one go back (in case of problems)?
Can SOMEONE from Dell comment on this? Any chance of the Nvidia problem fixed here?
@Dell-BradL, ????

Anyone reading this thread should immediately make sure UEFI Capsule Updates is disabled in whichever version of BIOS is running, pre-2.11.0. Otherwise, WU could force-install 2.11.0 without permission.
I pinged my Dell contacts...

I will myself not touch this one (given that it's a one-way street) until Dell says something about the Nvidia lock-up problem.
I have been stable for 155 days with BIOS 2.10 and Turbo "off" on my Linux system. However this is not a solution, it's a work-around, that cripples some of the functionality I paid for.
Dell really needs to contribute to this discussion. Until then I'm staying with something that at least doesn't cause productivity loss.
