Title:
  Ralink wifi driver works fine on 12:04 but causes kernel panic on
  12:10

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  On a Fujitsu Lifebook, I did a dual install of Windows 8 and Ubuntu 12:10.
  For wifi it uses Ralink RT3290

  To get the wifi working I got the driver from the Ralink web-site.
  I followed the install instructions mentioned: 
  http://rricketts.com/installing-ralink-rt3290-wireless-drivers-in-ubuntu-12-04/

  I was then able to connect to the wifi, but ubuntu was then very unstable.
  I was never able to do more than about 30 seconds of surfing with firefox.
  The OS would crash sometimes even before firefox was loaded.
  Each time, I saw the following on the screen:

  +++++++++++++++++++++++++++++++++++++++++++++
  Kernel panic - not syncing: Fatal exception in interrupt
  panic occurred, switching back to text console
  [drm] nouveau 000:01:00.0: no native mode. forcing panel scaling
  +++++++++++++++++++++++++++++++++++++++++++++

  
  Had the following in /var/log/kern.log ( which may or may not be relevant ):
  RT3290_AsicTxAlcGetAutoAgcOffset: Incorrect desired TSSI or current TSSI

  The work around I found that entirely got rid of the problem was to  switch from  Ubuntu 12:10 to 12:04.
  It is now working fine on my machine.

  So it looks like we have one of the following:
  (i) I've done something silly
  (ii) there is a bug in 12:10 causing the crash
  (iii) there is a bug in the ralink driver
  (iv) something else

  
  Here's more of the kern.log
