new kernel fails to boot due to DRM lock issue (intel)

Hi,

as Martin

yesterday I anticipated that the new DRI causes my kernel to panic while 
booting. tue do an already initialized mutex.

I cannot attach screenshot, so I pasted it here:

Here an extract:

lockdebug_alloc()
_mutex_init()
intel_dp_init_connector()
intel_dp_init()
i915_driver_load()
drm_dev_register()
drm_pci_attach()
i915drmkms_attach_real()
config_mountroot_thread()
cpu0
