i tried some stuff again, and it seems that what fixed the problem was not the different kernel but the nvidia driver i installed. right now it seems the bug is related to Nouveau driver or to unity of both. the weird thing though is that the bug repeated itself also after i stopped the x with 'service gdm stop'.
i am currently investigating more. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776306 Title: system freeze on suspend, natty, hp dv6 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
