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: [] :jfs:jfs_flush_jou= rnal+0x26a/0x27d Sep 19 13:08:04 oenone kernel: [] dispose_list+0xde/= 0xf7 Sep 19 13:08:04 oenone kernel: [] :jfs:jfs_umount+0x= 30/0xe5 Sep 19 13:08:04 oenone kernel: [] :jfs:jfs_put_super= +0xd/0x5e Sep 19 13:08:04 oenone kernel: [] generic_shutdown_s= uper+0x60/0xf0 Sep 19 13:08:04 oenone kernel: [] kill_block_super+0= xd/0x1e Sep 19 13:08:04 oenone kernel: [] deactivate_super+0= x6a/0x82 Sep 19 13:08:04 oenone kernel: [] sys_umount+0x249/0= x25a Sep 19 13:08:04 oenone kernel: [] audit_syscall_entr= y+0x141/0x174 Sep 19 13:08:04 oenone kernel: [] 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= =2E IMHO it is a regression.
