I hope this will help to investigate the issue and hopefully you can reproduce it as well. I'm using vanilla 3.0.4 kernel + xfs as root filesystem and had detect hanging taks with 120s set. You'll then see that the bonnie++ command get's stuck in xlog_grant_log_space while creating or deleting files. I was using a SSD or a fast Raid 10 (24x SAS Disks) - i was not able to reproduce it on normal SATA disks even a 20x SATA Raid 10 didn't work. I used bonnie++ (V 1.96) to reproduce it. Mostly in the 1st run the bug is triggered - sometimes I needed two runs. bonnie++ -u root -s 0 -n 1024:32768:0:1024:4096 -d / I hope that helps - as i now have a testing machine and can trigger the bug pretty fast (10-30min instead of hours). I can also add debug code if you want or have one. Stefan _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
