I have seen this bug happen on an older laptop with a ipw2100 card and Intel 82801 card. I have seen people ringing the laptop via skype often, in order to make it lock on purpose. Moreover, it once happened with my laptop that it could not get out of the hang.
Since this bug is exploited by a very common instant messaging application, this becomes a security risk, because people from outside can lock other people systems on purpose as I just saw. ** This bug has been flagged as a security issue -- BUG() report in getnstimeofday: soft lockup https://launchpad.net/bugs/53216 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
