Package: mount
Version: 2.20.1-5
Severity: normal
Dear Maintainer,
I am also experiencing the symptoms of bug 581786. I don't know if the root
cause is the same, but I have more information for you.
Mount hangs and uses 100% CPU. It is in "R" state according to "top" and
refusing to die even with a kill -9 as root.
* What led up to the situation?
I wrote a cd-r with wodim and then attempted to mount it.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I tried control-c, I tried kill -15, I tried kill -9, both as myself and as
root. I tried running another mount process thinking that might unhang it but
it didn't.
* What was the outcome of this action?
The disc is not mount and mount is unkillable.
* What outcome did you expect instead?
The disc would mount, or an error message would appear.
