[arch-general] A bug report when installing bbswith, depmod:ERROR

[Liuyang]

  depmod: ERROR: Module 'hci_vhci' has devname (vhci) but lacks major
  and minor information. Ignoring

I got the message above after I update my system to the newest released
version. Then bbswith and bumblebee doesn't work now. I tried to
reinstall that two packages but it still reported the bug message. What
can I do?
PS: Forgive my pool English.
