Right - applying those 2 commits on top of v2.6.38-rc8-1-g2e12978 works - now
the issue is away.
And yes - now I've to look for the other of two bugs, which was introduced
between the tags v2.6.38 and v2.6.39, I think.
Is there's an easy way to check, whether a given checked out git tree contains
a specific commit id ?
