Development: The two deltas being incorporated have been committed to the upstream AFS tree, and have also been included in openafs 1.4.8.dfsg1-3, which was just synced into Jaunty. Patch: Attached at http://launchpadlibrarian.net/25828644/openafs_1.4.7.dfsg1-6%2Bubuntu0.2.debdiff - please see the comments for explanation of the version number. Steps to reproduce: Assuming that AFS isn't in use when you reboot, rebooting with a 1.4.7 or 1.4.8 client that doesn't include these patches should consistently trigger the bugs behind them. Regression potential: For both of these deltas, the changes are limited to the shutdown code, i.e. the functionality that's affected by the bugs, so I find it unlikely that they'll make anything worse, and empirically they seem to fix the oopses and hangs. was after openafs-client stop on server ubuntu hardy [ 99.016655] Starting AFS cache scan...found 45 non-empty cache files (2%).
