Comment 12 for bug 1265309

Hi Christopher, thank you for your answer. I know about this

But i don't have the https://launchpad.net/~brightbox/+archive/experimental - ppa installed.
I removed all system relevant ppa repositories especially for lvm2.

The ppa's which are enabled on the sytem are only updates for user programs, like hugin, darktable, gimp or problems with networking (mosh, gvfs). An - as I said - identical conifugurations (Software) are running flawlessly in two other systems with similar hardware (SSD).

When I find time, I will prepare a second hdd or make space for a second partition to reproduce on a clean system.
So long and thanks.

Axel
