Due to recent refactoring in EEH in:
commit b9fde58db7e5 ("powerpc/powernv: Rework EEH initialization on

a misleading message was seen in the kernel message buffer:
[ 0.108431] EEH: PowerNV platform initialized
[ 0.589979] EEH: No capable adapters found
This happened due to the removal of the initialization delay for
powernv
platform.
Even though the EEH infrastructure for the devices is eventually
initialized and still works just fine the eeh device probe step is
postponed in order to assure the PEs are created. Later
pnv_eeh_post_init does the probe devices job but at that point the
message was already shown right after eeh_init flow.
This patch introduces a new flag EEH_POSTPONED_PROBE to represent
that
temporary state and avoid the message mentioned above and showing the
follow one instead:
[ 0.107724] EEH: PowerNV platform initialized
[ 4.844825] EEH: PCI Enhanced I/O Error Handling Enabled

Good idea, thanks for the patch.

Hi Mauro,
I got a chance to test your patch, I applied your patch on top of
mainline kernel commit:8efcf34a263965e471e3999904f94d1f6799d42a and
booted and I don't see the message "No capable adapters found" instead I
see "EEH: PCI Enhanced I/O Error Handling Enabled" as desired. But I
have not injected any EEH.Hope this should qualify your patch.
