Hi, during playing with new ups i've caught an nice oops on reboot: http://imgbin.org/index.php?page=image&id=10253 probably the upstream is also affected.Hi, Paweł Are you using a clean 3.6.6 without any modify?yes, pure 3.6.6 form git tree with modular config.quoted
Looks like some threads has set itself to be UNINTERRUPTIBLE with out any design on switch itself back later(or the time is too long), are you accidentally using some bad designed module?hmm, hard to say. mostly all modules are loaded automatically by kernel.
Could you please provide the whole dmesg in text? your picture lost the print info of the hung task. And please try the latest kernel, the issue may already solved(if it is a issue...). Regards, Michael Wang
