I reproduced the PANIC by running lkp-tests with a Intel machine.
The reason is that the function early_is_amd_nb is called even if
running on Intel machine. At this case the misc_ids is NULL so the
PANIC occur.
I'll rework a patch to solve this problem, either restore the default
value of misc_ids with the original AMD one or not call early_is_amd_nb
on Intel platform.
Return when !AMD and !HYGON is the right thing to do. No point in checking
device ids which cannot happen in the first place.
All right, I reworked a new reversion which will return if it's Intel.
