** Description changed: System: Ubuntu 12.04.1 x64 Unity desktop --- lsb_release -rd; uname -a Description: Ubuntu 12.04.1 LTS Release: 12.04 Linux Voyager 3.2.0-36-generic #57-Ubuntu SMP Tue Jan 8 21:44:52 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux -- Have not experienced any severe problems with this system from Aug 2012 till Jan 20 2013, when kernel 3.2.0-35 was still the active kernel. 2013-01-20 21:01 kernel 3.2.0-36 was installed by the Ubuntu updater. No installation problems occurred. Ever since K3.2.0-36 was the active kernel, the following problem occurred: On every restart error messages like these could be read in /var/log/syslog: syslog:Jan 22 00:44:37 Voyager kernel: [ 3.624421] EXT4-fs (sda5): orphan cleanup on readonly fs syslog:Jan 22 00:44:37 Voyager kernel: [ 3.652470] EXT4-fs (sda5): ext4_orphan_cleanup: deleting unreferenced inode 2886456 syslog:Jan 22 00:44:37 Voyager kernel: [ 3.652671] EXT4-fs (sda5): ext4_orphan_cleanup: deleting unreferenced inode 2886232 syslog:Jan 22 00:44:37 Voyager kernel: [ 3.652688] EXT4-fs (sda5): ext4_orphan_cleanup: deleting unreferenced inode 2886450 syslog:Jan 22 00:44:37 Voyager kernel: [ 3.678434] EXT4-fs (sda5): ext4_orphan_cleanup: deleting unreferenced inode 2369342 syslog:Jan 22 00:44:37 Voyager kernel: [ 3.689458] EXT4-fs (sda5): 4 orphan inodes deleted - syslog:Jan 22 00:44:37 Voyager kernel: [ 3.689462] EXT4-fs (sda5): recovery complete + syslog:Jan 22 00:44:37 Voyager kernel: [ 3.689462] EXT4-fs (sda5): recovery complete This happens no matter whether the system is rebooted (warm reboot) or shutdown and restarted later (cold reboot). The relevant thing is that in the session which is shutdown the active kernel has to be K3.2.0-36. - The error will be detected in the next session started after reboot. + The error will be detected in the next session started after reboot. The workaround was going back to K3.2.0-35. During the first reboot the errors left behind by the previous K3.2.0-36 session were cleaned up. From then on sticking with K3.2.0-35 the errors would not return after any reboot. Conclusion: ---------------- Telling from the symptoms Ubuntu 12.04.1 with K3.2.0-36 does not umount the root filesystem properly or does some other bad thing to leave behind orphaned inodes. Returning to K3.2.0-35 will work around the problem Note: ------- (1) I have seen this problem on 3 different machines (different hardware) running Ubuntu 12.04.1 x64 and Ubuntu 12.04.1 x86. - So it is not a problem caused by a flaw of one special machine. - (2) I have seen the same problem after updating Ubuntu 12.10 from K3.2.0-17 to K3.2.0-22. This suggests some change in the - latest kernel editions which is common to the current Ubuntu kernels may be involved. + So it is not a problem caused by a flaw of one special machine. + (2) I have seen the same problem after updating Ubuntu 12.10 from K3.5.0-17 to K3.5.0-22. This suggests some change in the + latest kernel editions which is common to the current Ubuntu kernels may be involved.
