Hi Johan,

I thought I'd just ping you quickly about this issue - did you get a
chance to look at the log files, and if so did you figure out what's
going on?

If on the other hand you don't have time to look into the issue, let me
know if I should file this issue in the kernel.org bugzilla (or
anywhere else) so as to avoid it being forgotten about (also note that
the logs will be expired from filebin.net after a couple of weeks).
