[Bug 661682] [NEW] [STAGING] rt2860sta drops out when running on battery power, worked in Lucid

[TH]

Public bug reported:

I have an Asus Eee 1000HE with a RaLink RT2860 wireless controller. In
Lucid Lynx, I could reliably connect to my 802.11g access point using
WPA (it has never worked on my 802.11n access point and this bug is
documented elsewhere).

However after upgrading to Maverick, the wireless connection usually
drops out when I unplug the AC adapter and run on battery.
NetworkManager tries to reconnect but is unsuccesful, after a while no
wireless networks show up in the scan result. The following is recorded
in the syslog when this happens:

Oct 16 12:30:32 eee kernel: [30073.089686] ===>rt_ioctl_giwscan. 2(2) BSS returned, data->length = 292

Oct 16 12:37:12 eee kernel: [30473.084281] ===>rt_ioctl_giwscan. 2(2) BSS returned, data->length = 292

After restoring AC power, these error messages stop and NetworkManager
is able to reconnect to the network.
