Address verification fails after AsRock B550 Taichi BIOS update

[mpartel]

After I updated the mobo bios from 2.10 to L2.71, this module started failing here.

I see address = 0xa20 but verify = 0xffff :raised_eyebrow:

If I remove the address != verify check, then the module seems to work correctly.

Any idea what's going on here?

I don't see a similar check in nct6683.c so I wonder, what is the verification for?
