Comment # 9 on bug 1106005 from Markus Zimmermann

Sorry, this got lost in my inbox. We can keep this closed. I never found anyone
else who had the same problem via Google over multiple months. We have several
other servers with the same hardware configuration and software versions but
only this one has this exact problem. Two weeks ago I got so mad that I wanted
to upgrade to 15.1 but after just the usual update the server couldn't boot
anymore. I simply moved everything. We dumped the server then.
