[URGENT] cannot unmount USB drives on 10.04

[kakyoism]

unmount seems to hang forever.... I then usually would just unplug my drives. Then maybe 20 minutes later there is a pop-up error box saying

Unable to stop MyDrive" DBus error .... did not receive a reply. Possible causes include: the remote application did not send a reply

It's urgent! Please help!

below is my dmesg at the time when umount hangs.

They are all NTFS drives. Here is my dmesg (partial, the complete one was too long to post here):

This might be different, if not probably so, but I've noticed that occasionally when I leave an external drive or another partition mounted for an extended period of time, I won't be able to unmount anymore because I don't "have permissions." So I just shutdown the system and unplug the device then.

Thanks, but that sounds pretty wrong to me. On Hardy or later there wasn't this problem at all.

[iponeverything]

It may be a known bug, I found this with

http://www.google.com/search?hl=en&source=hp&q=Unable+to+stop+DBus+error+site%3Alaunchpad.net

If this looks like the same bug that you have encountered, it will help to raise its profile if you add a comment to the bug report.

If it does not look like the same bug, look over a few of the other launchpad matches and open a new report if you find that its a new bug..

[kakyoism]

is there a solution to this problem?

I'm going crazy about this!

I've seen quite a few kernel upgrades but this problem persists. It never happened to me in Hardy!

[kakyoism]

Still the same.
I can't stand this anymore. The only way to solve this problem so far is to press the power button. I don't think my machine would like that.
