I think there are really two separate bugs going on here; 1) For some reason the Intel chipset doesn't like something and gives up 2) When it cleans up from (1) it panics
It looks to me like 3.5.0-19-generic has fixed the panic on my box; although I still get a black screen - but that looks like a separate monitor-presence detection problem: [ 23.572] (II) intel(0): Output VGA1 disconnected [ 23.572] (II) intel(0): Output HDMI1 disconnected [ 23.572] (II) intel(0): Output DP1 disconnected [ 23.572] (WW) intel(0): No outputs definitely connected, trying again... [ 23.572] (II) intel(0): Output VGA1 disconnected [ 23.572] (II) intel(0): Output HDMI1 disconnected [ 23.572] (II) intel(0): Output DP1 disconnected [ 23.572] (WW) intel(0): Unable to find connected outputs - setting 1024x768 initial framebuffer [ 23.572] (II) intel(0): Using default gamma of (1.0, 1.0, 1.0) unless otherwise stated. [ 23.572] (II) intel(0): Kernel page flipping support detected, enabling [ 23.572] (EE) intel(0): No modes. [ 23.572] (II) UnloadModule: "intel" [ 23.572] (EE) Screen(s) found, but none have a usable configuration. So, I'd say the oops itself is fixed; Markus - is the same true for you?
