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://
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_
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
