Comment 5 for bug 1538049

Installed a system with Debian testing and the crash does not happen there. That left two things: the additional security fixes we got or the kernel. And it was not the security fixes... Should have tried a different kernel sooner. Neither an old 4.2 based one nor the pending 4.4 are causing this. Only the current 4.3 based one. Maybe some Xen related stable patches did get mis-applied or not applied at all. Who knows. Will concentrate on the coming 4.4 and if I am happy, close this report.
