Christopher, I've already tried this earlier in the process (tried to bisect
the kernel), but failed on it. Also I guess, bisecting is not really

Christopher, I've already done this. First of all, I tried Ubuntu. But this was
not very successful. It advanced up to the 'Ubuntu' writing. From there on, the

Hans-Peter, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com

Hans-Peter, would you have some documentation to support this conclusion? The
following documentation discusses nothing about SSDs, but instead discusses
VMWare with 2.6 kernels, which you are not using:
Christopher, please see http://wiki.ubuntuusers.de/SSD/Scheduler and search

Hi Christopher,
thanks for your help. I had visited the HP download site. The enhancements of
3.14 were a more reliable flash process - so I didn't install it at first. But
to be on the safe side, I did now.
