Seems to be a sheduler issue it can be investigated by doing a diff of kernel configs according to this forum post (also on ubuntu there are similar kernels) http://forums.opensuse.org/showthread.php/480993-Kernel-desktop-vs-default?p=2507420#post2507420 http://forums.opensuse.org/showthread.php/480993-Kernel-desktop-vs-default?p=2507420#post2507420
Desktop kernel is configured differently and less conservative than default in the following areas: - Processor type and features: - Timer frequency, (set to 300Hz on '-default' and 1000Hz on '-desktop'). - Preemption model, (set it to the highest option 'Low latency desktop'.)
