Not exactly ...
The commit messages are Ok, but the description of the problem is even more informative.
E.g. a commit message such as "fix random system hang issue" is informative, but I could really use the description in what circumstances these hangs have been experienced etc. so that I can figure out whether it might be the same problem as mine. That's, I suppose, the reason you put the issue ID in the commit message, isn't it ?
