I've tested this a little further. The behavior is independent of the kernel version used (tested back to 2.6.37). My SSD is also fine and a freshly created xfs partition shows no problems, too. Please note that the affected partition is used very heavily here (several git trees, daily backups of / and the Gentoo build-dir reside there). So it appears that the observed "hangs" are the result of a strongly aged file-system. -- Markus _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
