Comment 35 for bug 444192

Just loaded Lucid Beta 2, which cannot boot with standard parameters. It ends in a screen with no text, some coloured background and a white square in the middle of the screen. Mouse works, keyboard works, but the only thing it can do for the user is to go to a console, such as via CTRL+ALT+F2, where there are many error messages, all referring to the same thing (which has been a problem since Jaunty for many!!!!):

[603.412359] [drm_radeon_fence_wait] *ERROR* fence (f3a55820: 0x000000115) 516ms time out

[610.972433] [drm_radeon_fence_wait] *ERROR* last signalled fence

[xxx.yyyyyy] [drm_radeon_fence_wait] *ERROR* fence (f3a55820: 0x000000115) 516ms time out going to restart GPU

Where xxx.yyyyyy indicates that these numbers are different for each error message

The apport report submitted above is done after booting with:

noacpi
noapic
nolapic

With these parameters Lucid Beta 2 boots ok, but as can be seen in the attached screenshot there is a strange error in the network-manager icon in the systray
