  168c:002b Atheros AR9285 extremely slow & unstable

Status in “linux” package in Ubuntu:

Bug description:
  I just did a fresh install of Ubuntu 11.04 64-bit on my hp pavilion dv6, everything worked out of the box except for the Atheros AR9285, which used to work like a charm on 2.6.35 kernels.
  It connects to every kind of wifi network, but after a few minutes connection became unstable, and is slow as hell - unusable.
