Issue #455 has been updated by Walter Sonius.
Quick and dirty fix!
The same issue on MSI H87-G43 (ms7816 rev1.2) appears, although NCT6779D is supported however not the specific model with ID`0xc563`. In the "nuvoton.c" source file from the "superiotool" alter the ID on line number 551 from `0xc562` to `0xc563`. Since I don't know how to add an extra ID/condition to the source file, this will break detection for someone with the `0xc562` chip. Can someone please do pull request for superiotool?
https://github.com/coreboot/coreboot/blob/main/util/superiotool/nuvoton.c ` {0xc562, "NCT6779D", {` replace with ` {0xc563, "NCT6779D", {`
The first time using `superiotool` without this fix, it will detect wrongly the Aspeed chipset just like the Original Poster reports but returns `chip_id=0xc563` hinted multiple times. Subsequent runs of the `superiotool` won't find any chipset anymore but will end with `No Super I/O found`...

Fixed superiotool output, replaced line 551 ID c562 > c563 and it will dump/report registers: ``` sudo ./superiotool -dV superiotool r Probing for ALi Super I/O at 0x3f0... Failed.

Without debug symbols I can't use gdb to provide more useful information.
