Run it through mcelog to see what it decodes to:
dmesg | mcelog --ascii

Is the system crashing? Or do you just see this message but
no other bad effects?
Does is happen every boot? Or was this a one time message?
Can you grab some context lines from dmesg (say 40 lines
leading up to this message) to see what else was going on?

that system is normally not crashing. as far as i know, there are no
other bad effects
it happens during every boot.it is not a one time message.

Looks like mcelog has trouble decoding this. Have you updated mcelog to
the latest version in your distro?

@Tony, I'm hoping you'll be more successful in decoding the error by
hand.

So this is looking like another case where an error is
logged during BIOS bringup, and Linux finds the error
when it scans all machine check banks during boot.
The earlier logs you sent showed a value of ee0000000040110b
in the machine check bank status register. Not sure why
mcelog had trouble with this(*).
Upper bits say: VALID OVER UC MISCV ADDRV
Low 16 (MCACOD) bits say: FILTER CACHE ERR GENERIC LEVEL=3
So BIOS did something to trigger some issues in the L3
cache (more than once since the overflow and filter bits
are both set).
I think (but am not 100% sure because I don't have an
internal decoder that knows about this specific CPU model)
that the error was a write-back to MMIO (this matches other
cases where we've seen BIOS trigger some error and left the
logs for Linux to find at boot). It's not quite the same
because the address logged for you is 160000080, where the
previous cases has addresses below 4GB. But some platforms
include MMIO above 4GB, so this is still plausible.
Advice we have given before is to attempt to log a bug
against the BIOS with the vendor of your system. But the
last person to try this reported no success.
Or, you could ignore it. It appears to not have any
side effects.

(*) Can you send a snip from the raw dmesg output that starts
a couple of lines before:
... [Hardware Error]: CPU 0: Machine Check: 0 Bank: 5 ...
and continues a couple of lines past
... [Hardware Error]: PROCESSOR 0:306d4 ...
and I'll take a look at why mcelog choked.

We do have that __mcheck_cpu_apply_quirks() and cfg->bootlog thing to
shut it up. Because it all sounds like BIOS forgot to clean up after
itself and the kernel seeing those errors is doing nothing but puzzle
people.
And it's not like there's anything we can do about the erros...
Anyway, just thinking out loud.

I guess I didn't explain that very clearly. I need all the lines
in betweeen.
How about this:

The problem is that "mcelog --ascii" is expecting the first line to
look like:
CPU 0: Machine Check Exception: 0 Bank 5: ee0000000040110b
This seems to have been broken by commit:
cd9c57cad3fe ("x86/MCE: Dump MCE to dmesg if no consumers")
relevent part is this ... where we now conditionally include the
word "Exception".
-static void print_mce(struct mce *m)
+static void __print_mce(struct mce *m)
{
- int ret = 0;
-
- pr_emerg(HW_ERR "CPU %d: Machine Check Exception: %Lx Bank %d: %016Lx\n",
- m->extcpu, m->mcgstatus, m->bank, m->status);
+ pr_emerg(HW_ERR "CPU %d: Machine Check%s: %Lx Bank %d: %016Lx\n",
+ m->extcpu,
+ (m->mcgstatus & MCG_STATUS_MCIP ? " Exception" : ""),
+ m->mcgstatus, m->bank, m->status);
While this is a bit easier to read, no new information is included as we
do print the value of m->mcgstatus.
Sadly, the change was made back in v4.10 ... so reverting it won't
help all the people running kernels built in the last fifteen months :-(
I'll see if I can get Andi to take a patch for mcelog to accept the
line with or without the " Exception".
Oh ... one more thing. Did your e-mail client line wrap that last line?

That should all be on one line.

Well, mcelog should decode the error signature regardless whether it
says "Exception" or not, IMO.
