As you can see above, the trouble starts with: "... CPU 0 Unable to handle kernel paging request ..." Does your system also lock up when you leave WiFi off and try to access swap space? (i.e. by filling up RAM, I have no exact proposal for the experiment, but I trust you understand my intention) Otherwise, please check whether your RAM filling up just before your system suffers these lock-ups. -- You received this message because you are subscribed to the Google Groups "loongson-dev" group.
