I was curious so i reverted to a previous kernel version and i tested 2.6.31.12. The bug is there and my debian system with 4GB of RAM gives the Input/Output error managing 300000 files. So, IMHO, this bug is related to something that changed before 2.6.32. If i'll have some time i'll check previous versions of already built kernels i used before and let you know what i found. If i were you, Christian, backup all your data asap. When corruption happened to me reiserfsck didn't help at all, even with rebuild-tree option... LVM snapshots saved me a lot of work and time! For the record i was able to verify this bug with setfacl version 2.2.47 and 2.2.49, packaged by debian: http://packages.debian.org/lenny/acl The -R option is there for recurse.
