I can't see how it directly causes your issues, but it will slow anything down to almost a grinding halt on systems with more than say two cores. Can you run with CONFIG_DEBUG_LOCK_ALLOC / and CONFIG_PROVE_LOCKING disabled/ It might be worth if you have other really heavy debugging options enabled, too. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
