Summary: radeon with modeset option causes oops as secondary
adapter (vgaswitcheroo)
Product: Drivers
Version: 2.5
Kernel Version: 2.6.38.3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Video(DRI - non Intel)
AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
ReportedBy: jcnengel@googlemail.com
Regression: Yes

kernel log
System: Lenovo ThinkPad T500
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset
Integrated Graphics Controller (rev 07)
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3650
using vgaswitcheroo
Trying to load radeon (as a module or in kernel) with modeset not explicitly
disabled causes a kernel NULL pointer dereference if i915 has initialised the
fb console already.
That behaviour did not occur in 2.6.38, only after upgrading to 2.6.38.3
(haven't had the time to bisect yet).
If I disable switching in the BIOS and move to the radeon card as exclusive
adapter, everything works fine. with dual graphics stack

don't suppose anyone can bisect this? you'd only have to bisect drivers/gpu
I can probably try and reproduce it next week.
