I had the same issue, fixed it by updating to the latest BIOS + enable & active security boot, try it might work.
My settings are ENABLED and STANDARD for Secure boot, just updated BIOS yesterday...no luck still, no clue what's happening and I don't know if it's the Beta or if my computer is dying...
Is that kernal power the only event of note in the Event Viewer or is there anything else happening around the same time? Also does it only happen with BF6 or is it happening with other games or even general use as well?
Other things after it, but that's the only "critical" thing, and yes, so far, onl, - and reliably - BF6 Beta. It's become unplayable to me...which is a real shame.
