Date: Thu, 21 Jul 2011 11:19:15 +0200 From: Michael Brade <brade@...ormatik.uni-muenchen.de> To: linux-kernel@...r.kernel.org Subject: 2.6.39, 3.0.0-rc7+: complete system freeze with rsync on big directory Hi, this is perfectly reproducible: with vanilla 2.6.39.x and 3.0.0 from yesterday's git my system completely freezes after a minute or so when I do rsync -cavSH -n /source/ /dest/ Watching htop, it freezes only after the caches are full but not immediately when the caches are full. No Alt-SysRq-magic is working anymore, nothing responds at all after the freeze. This is on tty1, no X server running. Note the -n which means dry run. I also mounted both directories read-only, so it's not the write commands. I am using XFS on both directories, one is mounted with iscsi, the other is local and encrypted with loop-aes. The directory size is >20 GB, 4000-6000 files. I first noticed it when a cp -a /source /dest froze the system. When I go back to 2.6.37.6 it works fine. I didn't try 2.6.38 yet. I am running this on a Dell Vostro, amd64, 6 GB RAM, 8x Intel Core i7 CPU Q 740 @ 1.73GHz. Any ideas how to debug this despite the freeze? Do you need my kernel config? Do you need any other info? Please CC me. thanks, Michael -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
