I'm running a 2.6.20 kernel on my macbook. When running an openGL
application, if the opengl window's region is moved somewhere outside
the screen limits, then keyboard locks, I can only move the mouse,
nothing response. I can only reboot the box by pressing the power button
5 seconds. /var/log/syslog contains that :
kernel: [drm:i915_wait_irq] *ERROR* i915_wait_irq: EBUSY -- rec: 730561 emitted: 730570
The macbook uses an intel card :
00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS/940GML and 945GT Express Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)
