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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
