Thinkpad L520 won't boot without nox2apic kernel parameter

I can't boot using any of the stock arch kernels since 3.2.0 unless I disable x2apic.  There's a bug report at https://bugzilla.kernel.org/show_bug.cgi?id=43054, apparently it's affecting other thinkpads as well. 

If anyone else is having problems, try adding nox2apic to your kernel command line or compiling a kernel without CONFIG_X86_X2APIC.  And be aware that installing arch using the net install iso will require using this parameter or ignoring the linux package when downloading/installing packages. 

Booting without disabling x2apic was completely locking up @ the line:
"ACPI: EC: Look up EC in DSDT"

Interesting.  No issues here with a T410.
