What is the actual panic message? For the archives the trace was: panic(b6ae0c) at panic+0x154 mtx_enter(0) at mtx_enter+0x8c drm_update_vblank_count(2a0fcdf8,e000a000,b6ae78) at drm_update_vblank_count+0x4b8 drm_handle_vblank(2000611,82720e) at drm_handle_vblank+0xd8 r100_irq_process(a19ca0) at r100_irq_process+0x110 radeon_driver_irq_handler_kms(0) at radeon_driver_irq_handler_kms+0x28 openpic_ext_intr() at openpic_ext_intr+0x274 extint_call() at extint_call --- interrupt --- at 0xe7055e1c drm_wait_vblank_ioctl(e0732f00,e06b9b84,e7055c60) at drm_wait_vblank_ioctl+0xb2 drm_do_ioctl(251571d0) at drm_do_ioctl+0x298 drmioctl(25157100,e7055ca8,990000,c010643a,3a033428) at drmioctl+0xbc
