if you have the technical capability to ignore all noinstr warnings
coming from the mce code, please do so.
I have a patchset to address that but more important work preempts me
constantly from cleaning it up and sending it out properly. ;-\

Hi Borislav,
Thanks for the feedback, We have ignored these warnings from mce.

Any progress? Anything I can help with?
I was hoping that 5.17 would fix this but I just merged Linus's tree
with netdev today and the warnings are still there :(

Hmm, weird. The set which is supposed to address this got merged last
week:
7e740ae63504 ("Merge tag 'ras_core_for_v5.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip")
How exactly can I reproduce what you're seeing?
I need to merge which commit into which branch and then use which
.config to reproduce?
Thx.
