Subject: `GHES: Failed to enable APEI firmware first mode.` on AMD board

Dear Linux folks,


On the ASUS F2A85-M PRO since at least Linux 4.14 (up to 5.17-rc1) I am
getting the failure message (level info) below:

[ 2.054690] calling ghes_init+0x0/0xee @ 1
[ 2.054918] GHES: Failed to enable APEI firmware first mode.
[ 2.054921] initcall ghes_init+0x0/0xee returned 0 after 220 usecs

I failed to trace the probe function `ghes_probe` although it’s listed
under the available filter functions.

$ sudo grep ghes_probe /sys/kernel/tracing/available_filter_functions
ghes_probe

The trace of `ghes_init` is attached although it is probably useless as
the question is why the probe function succeeds.


Kind regards,

Paul
