Bug Description

Binary package hint: mountall

When starting Karmic Koala mountall continues to run non-stop reading and writing to the local harddrive creating a very noisy system (harddrive read/write noise) and creating a severe performance boost (I/O to the harddrive is taken up by mountall).
The only workaround at the moment is to kill the process mountall manually from the command line.

I'm not aware of any code in mountall that would write to the hard drive.

Please run "sudo strace -p PID_OF_MOUNTALL" before killing it, and attach the output of that command to this report.

Here is what I could capture from the mountall daemon performing mysterious read write activities. I tried to send it to an output file but because the only way to get it to stop is to sigterm it with the kill command I was only able to capture what was left in the screen buffer. It's all repetitive so should be easy enough to see what is going on.

Is your windows partition hibernated by any chance?

The Windows Partition was shut down normally about two years ago.
It's only there for historical reference and data.
The issue occurred about 5 days after the upgrade to Karmic Koala and after several
sudo aptitude update && sudo aptitude safe-upgrade

Still curious why the mountall would use 100%CPU and I/O

No idea why your windows partition cannot be mounted, but it looks like failing to mount it triggers another attempt to mount it
