[Bug 1250027] [NEW] Lenovo ThinkPad T420s fails to boot with discrete graphics

 

Public bug reported:

Booting a ThinkPad T420s with discrete graphics enabled in the causes a
hang during the boot.

The hang happens somewhere during udev startup, I think.

As described in #1007138, adding pci=noacpi to the kernel command line
fixes the problem.
