I would try to add some printfs (or used dtrace - whichever is easier for you) to see what's going on. Or you can even use pciconf to directly sneak a peek at what's reported by the hardware, e.g.: # pciconf -r pci0:0:24:3 0xa4 1c881880 You can read the BKDG to see how to interpret the value - search for F3xA4.

I gave up the DiodeOffset recently because a lot of BIOSes do not set any meaningful values. Instead, I added a tunable for that.

I also believe it works well but errata is errata. If vendor says we shouldn't use it, then we shouldn't. In fact, I am just following Linux as an example here but I have no problem with turning this into a warning message, either.
