OK, I've done test. On 2.6.22 I was unable to trigger the warning. On 2.6.23-rc6 I get the following warning in about 3/4 of all unmounts: Sep 19 13:08:04 oenone kernel: WARNING: at fs/jfs/jfs_logmgr.c:1643 jfs_flush_journal() Sep 19 13:08:04 oenone kernel: Sep 19 13:08:04 oenone kernel: Call Trace: Sep 19 13:08:04 oenone kernel: [<ffffffff8860f962>] :jfs:jfs_flush_journal+0x26a/0x27d Sep 19 13:08:04 oenone kernel: [<ffffffff8029fca1>] dispose_list+0xde/0xf7 Sep 19 13:08:04 oenone kernel: [<ffffffff885fd003>] :jfs:jfs_umount+0x30/0xe5 Sep 19 13:08:04 oenone kernel: [<ffffffff885f9a31>] :jfs:jfs_put_super+0xd/0x5e Sep 19 13:08:04 oenone kernel: [<ffffffff8028ef8f>] generic_shutdown_super+0x60/0xf0 Sep 19 13:08:04 oenone kernel: [<ffffffff8028f02c>] kill_block_super+0xd/0x1e Sep 19 13:08:04 oenone kernel: [<ffffffff8028f0f7>] deactivate_super+0x6a/0x82 Sep 19 13:08:04 oenone kernel: [<ffffffff802a2184>] sys_umount+0x249/0x25a Sep 19 13:08:04 oenone kernel: [<ffffffff802616ff>] audit_syscall_entry+0x141/0x174 Sep 19 13:08:04 oenone kernel: [<ffffffff8020be8c>] tracesys+0xdc/0xe1 Sep 19 13:08:04 oenone kernel: This is on a partition of a usb mass storage device with 2K sector size.
