Subject: Lost ps/2 input in 3.2.5 (aka PCI: Rework ASPM disable code)

Hi,

so I finally decided to commit 3.2.5 into the opensuse kernel. However
it does not even work on my laptop.

Both keyboard and touchpad are not detected. They are connected via PS/2.

I see
PNP: PS/2 appears to have AUX port disabled, if this is incorrect please
boot with i8042.nopnp

Without that patch this warning is gone and devices properly enumerated.

thanks,

Does it also work if you pass pcie_aspm=off when you boot?

I thought Matthew had a patch queued up for 3.3-final that would fix
this. Matthew, what happened to that?

Well, bother. Can you give lspci -vvv before and after the patch, along
with dmesg?
