John, does the below hunk help booting?

You might still see

  "Unexpected threshold interrupt at vector f9"

or so but you should still be able to boot.

@Yazen, btw look at the bugzilla entry - dmesg has a bunch of MCEs during boot:

[    2.001178] mce: [Hardware Error]: Machine check events logged
[    2.001302] mce: [Hardware Error]: CPU 4: Machine Check: 0 Bank 1: d8200000000a0151
[    2.001309] mce: [Hardware Error]: TSC e45ee7124 MISC d01b0fff00000000 SYND 4a000000 IPID 100b000000000
[    2.001317] mce: [Hardware Error]: PROCESSOR 2:810f10 TIME 1538271297 SOCKET 0 APIC 4 microcode 810100b

how do we decode those new ones if the EDAC decoder is not loaded? I.e.,
by hand? We probably need some IPID mapping or so...

And also, why is his box spewing so many of those, it is trying to tell
us something. :-)

Thx.

I happen to have the same notebook with the same BIOS and the same
problem. So let me test it :) (see below).

That's correct, with your patch I see those messages but kernel boots!

Is that a valid material for a patch? If so, you can add my:

Even better! I might ask you do to a couple more tests if you don't
mind. But later, once we've figured out what exactly we should do.

Good.

Thanks.

So yeah, I think that's small enough to be stable material.

Now, even if that is the proper behavior of *first* initializing and
setting up all the structures and only *then* setting up the IRQ handler
which accesses them, we still get:

> [    1.059187] Unexpected threshold interrupt at vector f9

and it probably will be better to initialize those structures earlier
so that we be able to actually process that thresholding interrupt
properly.

And doing that is not trivial because of this nasty order for xen -
see comment at end of arch/x86/kernel/cpu/mcheck/mce_amd.c - but that
shouldn't stop us to improve stuff on baremetal. So it'll take a bit
longer to do.

That's why it would be cool if you could test some fixes later on your
machine. And pls delay upgrading your BIOS if, in the course of that
fixing, someone tells you to do so because then that early thresholding
will be fixed and we won't be able to test the final fix. :-)

You can always upgrade it after that, if it is ok.

Thanks a lot!

Yeah, and note that it's also a clear and serious regression, so even if 
the fix is more involved there's a justified case for fixing the bug and 
marking it -stable - affected systems are crashing otherwise.

Thanks,

Sure! E-mail me whenever you have something to test, I'll stick to the
current BIOS version, thanks for the notice!

Yeah, so I need to hammer on this current fix a bit with a hotplug
script to make sure CPU hotplug still works because that "fixing" here
came after the hotplug rewrite...

Stay tuned.

The more involved fixing we'll do later, when there's time.

Right, I think we may want to bring back the separate decoder ring/queue that
we used to have. Do you think that would be okay, or is there another method
that would be better?

Thanks,

The problem with early MCEs is that stuff is simply not ready to load
any decoding modules yet.

So either we could do a userspace tool to do the decoding or we can
simply reuse the mce_amd.c code and *echo* the error stanza from
userspace and it'll dump the decoded info. This done on the same
machine.

And *actually*, we already have all the code in mce-inject.c - so
decoding would simply be an MCE injection with type SW_INJ. I'm looking
at do_inject():

        if (inj_type == SW_INJ) {
                mce_inject_log(&i_mce);
                return;
        }

Ha!

That's soo cool and for lazy people like me :-)
