I think this bug might be a duplicate of bug #146692 which describes the freeze on a Samsung Q45. On the q45 the last message before the freeze is the "ricoh"-message as well, but the freeze is caused by the module video.ko.
It would be interesting to know which graphics hardware is build into your notebooks, since there are different versions of these notebooks with either Intel or Nvidia graphics. So @ Sven and @ Andrei: Can you please tell if your notebook has either Intel or Nvidia- graphics? (eg. "lspci | grep VGA") -- All updated kernels starting from 2.6.24-14 are failed too boot the system (it hangs) on my samsung Q70 laptop - reason is the problems with a driver for built-in ricoh cardreader. https://bugs.launchpad.net/bugs/216185 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
