I'll venture a guess here and say that Matt's reproducer won't trigger on your
machines.

Just to rule out any other issues which got fixed in the meantime, can you try
mainline Linux and see if you can reproduce your observation with it?

If so, you could share your crash core along with debug kernels yadda yadda so
that I can poke at it.

And before you do, make sure you have the latest BIOS and microcode installed on
that machine.

Also, where can I find full dmesg and /proc/cpuinfo from those machines which
trigger this?

Thx.
