Title:
  Wifi driver regression in 3.8.0-x kernels (works in 3.5.0-26)

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  My laptop is an HP dm1z, with a Ralink RT5390 wifi card (rt2800pci
  driver).

  I cannot connect to wifi networks reliably in 3.8.0 kernels. By
  reliably, I mean that the connection may happen, but will become
  disconnected after several minutes, and then cannot be recovered.
  During attempts to recover, NetworkManager will continuously re-
  request the wifi password. The problem is not related to wifi network
  strength (moving the laptop < 3 feet from the router does not solve
  the problem).

  If I boot into a 3.5.0-26 kernel, the connection works fine.

  I expected to be able to connect and stay connected to wifi networks
  using the 3.8.0 kernel.
