I also took a look myself and it turned out that my maildir, which contains the LKML messages of the last three months, is the root of the problem. I can now reproduce the bug, by simply running (e.g.): cp -al /var/backup/hourly.3/localhost/home/markus/.maildir/lkml/. /var/tmp/debug where /var is mounted as: "/dev/sda1 on /var type ext4 (rw,noatime,commit=60)" and /var/backup/hourly.3/localhost/ is a previous backup produced by rsnapshot. -- Markus -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
