Does the MCA log say anything useful?

I used your .config and saw an MCA in i8042_flush() (IIP in
__ia64_inb, BR0 in i8042_flush).  Can you try turning off
CONFIG_SERIO_I8042?  This was fixed a while back, but maybe
it got broken again.  And the i8042 probe happens much later
than your log indicates, so maybe you're seeing a different
problem.

P.S.  What is your firmware "acpiconfig" mode?  My eiger is
in "default" mode, in which accesses to non-existent I/O ports
cause MCAs.  But we don't officially support that yet because
of issues like this.  The supported modes allow accesses to
non-existent ports by setting either "single-pci-domain" or
"enable legacyprobe".
