Yeah I believe I should go back to f21 untill the figure things out no?If a BIOS version is missing from their support site, it's likely that a bug or an issue was reported that might have resulted in the board failing or causing instability of the system overall.

I would leave the system/BIOS as is and be patient for any followup updates. In the event that you see instability with your platform while on F22, downgrade the BIOS to F21.
