Message-ID: <nsxfvzov3em.fsf@closure.thunk.org> Date: Thu, 21 Mar 2013 17:39:13 -0400 From: Theodore Ts'o <tytso@....edu> To: linux-ext4@...r.kernel.org Subject: xfstest failure: #68, with data=journal I'm not sure why I wasn't seeing this test fail earlier, but I'm now seeing the following reliable test failure. I can repro on v3.8-rc3 (although when I took my baseline on February 21st it test #68 was passing), which is why I didn't let this hold up sending a PULL request to Linus. Regardless of why it wasn't failing earlier, I'm now seeing it failing reliably on two different testing setups, with the following kernel BUG: BEGIN TEST: Ext4 4k block w/data=journal Thu Mar 21 17:27:32 EDT 2013 Device: /dev/vdb mk2fs options: -q mount options: -o block_validity,data=journal 000 - unknown test, ignored FSTYP -- ext4 PLATFORM -- Linux/i686 candygram 9b2ff35753c0 MKFS_OPTIONS -- -q /dev/vdc MOUNT_OPTIONS -- -o acl,user_xattr -o block_validity,data=journal /dev/vdc /vdc [ 27.640833] EXT4-fs: Warning: mounting with data=journal disables delayed allocation and O_DIRECT support! 068 [ 81.197193] fsstress (3426) used greatest stack depth: 5724 bytes left [ 87.114210] fsstress (3425) used greatest stack depth: 5660 bytes left [ 98.464599] ------------[ cut here ]------------ [ 98.466113] kernel BUG at /usr/projects/linux/ext4/fs/jbd2/transaction.c:2016!
