Bug Description
I am using Kubuntu 10.04 64-bit and have disabled plymouth in order to see what exactly is going on during
startup/shutdown.
Almost everytime I shutdown/reboot my computer I see the following msg:
Unmounting weak filesystems...
mount :/ is busy
and then the computer shuts down.
On startup, I receive the msg that the drive (sda1 in my case) needs to be recovered.
I found a similar report here:
https:/
but applies to the 10.10 release, which is why I decided to file a report for Lucid.
I am worried that this can cause data corruption or loss. Please also note that many users may be unaware of the problem since most have plymouth enabled (therefore there are no msgs appearing during shutdown)
Please let me know if you need any more information. Thanks.
Description: Ubuntu 10.04.1 LTS
Release: 10.04
Need to mention that problems started when I installed KDE 4.5, did not have any unmounting problems with 4.4.2. I have also filed a report to KDE:
https:/ /bugs.kde. org/show_ bug.cgi? id=248539
Now, if I boot in recovery mode, drop to root console with network and login to my desktop from there, then shutdown/rebooting is clean and all devices are unmounted properly. Is that any helpful?
I attach an output of "lsof" taken right before the unmounting takes place.
