On Lenovo *60 laptops, make sure that you enabled modem on BIOS.
Otherwise both sound and wireless may hang due to a BIOS problem.  A
workaround is to add probe_mask=1 option to snd-hda-intel (force to
ignore modem).

Also, enable_msi=1 option for snd-hda-intel is worth to try.
This doesn't work reliably on many hardwares, though.
