https://bugzilla.kernel.org/show_bug.cgi?id=33812 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@xxxxxxxxxxxxxxxxxxxx ReportedBy: jcnengel@xxxxxxxxxxxxxx Regression: Yes Created an attachment (id=54942) --> (https://bugzilla.kernel.org/attachment.cgi?id=54942) 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 -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Fulfilling the Lean Software Promise Lean software platforms are now widely adopted and the benefits have been demonstrated beyond question.
