lstnmysphr: Thanks for the useful information. You are right. Kaspersky is definitively related, but there are instances on which I experienced the botched shutdown even after having deleted /.com_kaspersky_iswift_journal
However, in my case, in the event that Kaspersky is not run at all, deleting /.com_kaspersky_iswift_journal fixes the problem.
I have been performing some extra tests, and have found out new information:
- The shutdown message about unsuccessfully trying to unmount /Network/Servers, /home and /net appears on some correct shut downs as well (I am not sure if it appears always, or only sometimes). So this is not indicative of what is causing the problem.
- The file /.com_kaspersky_iswift_journal sometimes appears on reboot even if Kaspersky autorun is disabled, and without running Kaspersky at all.
- There are some cases in which even after having manually deleted /.com_kaspersky_iswift_journal, the computer won't shut down. But definitively Kaspersky is a factor in the problem. I experienced the bug after performing these steps:
1) Reboot with Kaspersky autorun disabled
2) Delete /.com_kaspersky_iswift_journal
3) Run Kaspersky
4) Enable Kaspersky autorun
5) Check that /.com_kaspersky_iswift_journal doesn't exist
6) Run and close Photoshop
7) Rebooted and it hanged up.
This is being difficult to debug because rebooting is quite time consuming.
vea1083: If you never had Kaspersky installed I think you are experiencing a completely different Lion bug, that coincidentally results in the same problem. All the rest of the people in this thread are relating our problems to Kaspersky Antivirus 8.0.2.460 for Mac (either currently installed or previously installed and uninstalled).
