XHCI_SPURIOUS_WAKEUP for Panther Point devices from Lenovo

Hello,

I was also hit by this bug. My device is a Lenovo Thinkpad S531 with Ivy Bridge respectively Panther Point components. The manufacturer of my UEFI/Bios (latest version 1.11) is Lenovo.

Attached is a patch that fixes this bug for me. It is narrowed down to devices from Lenovo. The patch applies cleanly to vanilla kernel 3.13.1 and is tested. It would be great if a similar fix could be applied to the mainline kernel and stable kernels.

I have never used anything else than Fedora 20 (initially kernel 3.11.10) on my machine and was never able to power off by doing a normal shutdown. The temporal fix from comment 60 works for me, too. There are several devices from Lenovo which are very similar to mine. Maybe all of them are affected.

Some hint if this patch doesn’t work for you: Perhaps you have to rebuild your initramfs. Xhci-hcd.ko was inside my initramfs and after just recompiling the modules in drivers/usb/host I had to rebuild my initramfs.

(Re-)building an initramfs with dracut:
dracut "" `make kernelrelease`

If there is anything else I can do to help fixing this bug, please ask.
