No problem. Something else to try: Are you by chance running with DMAR/VT-d enabled? If so, please disable it (either in the BIOS or with intel_iommu=off) and see whether that works around the semaphore hangs. Perhaps do this before trying out the patch, doesn't require a new kernel ;-) Thanks a lot, Daniel -- Daniel Vetter [email protected] - +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
