--- Comment #27 from darkbasic darkbasic@linuxsystems.it --- I completely removed tracers, changed slab allocator from slub to slab, completely disabled kernel debugging... it didn't help :( Can you please be more specific? Also, is there any way to check what the hell is happening? You spoke about kernel spending lots of cpu cycles in slab_alloc and slab_free but I have no clue how to debug it and developers seem not willing to help me.
