Hi, Looks like I ran into an ext3 bug (or at least the log says so). I got a bunch of messages like: ext3_free_blocks_sb: aborting transaction: Journal has aborted in __ext3_journal_get_undo_access<2>EXT3-fs error (device sda2) in ext3_free_blocks_sb: Journal has aborted EXT3-fs error (device sda2): ext3_free_blocks: Freeing blocks in system zones -Block = 228, count = 1 It happened while I was doing an "rm -rf" on a directory. The "rm" gave a segfault and now I can't unmount the filesystem: unmount says "device is busy", even though lsof reports nothing. The filesystem is on a USB hard disk. The actual dump is in attachment. I'm running Debian unstable with a custom 2.6.10 kernel on a 1.6 GHz Pentium-M. Jean-Marc -- Jean-Marc Valin Université de Sherbrooke
