I searched about 15 months of log files - both error messages appeared for the first time about 14 days ago. Kernel 3.2 is much older, and the system survived _much_ longer uptimes previously. Either it?s not a kernel problem, or that kernel problem is exposed by some recent (max 6 weeks) change in Xorg, KDE, ... etc. Unfortunately there were a lot of changes in that time. cu, Knut
