Comment (by Quozl):

 * restoring the VivEXASync code made no change, the problem persists,
  * by adding selective printk in gckKERNEL_Dispatch we find the failing
 request is gcvHAL_ALLOCATE_LINEAR_VIDEO_MEMORY, and the arguments at
 call to gckOS_Sprintf] are invalid,
  * reason for use of gckOS_Sprintf is unknown,
  * removing the call to gckOS_Sprintf seems to fix.

 Next step; find what funcName member of structure is used for.
