I have upgraded to intrepid the PC on which I was experiencing the hard lockups. And the lockups have disappeared. I have also upgraded to hardy a laptop on which I was running gutsy. And the lockups have appeared although by no means as frequently as I was experiencing them on the older desktop. I am experiencing about a couple of hard lockups a week, with the laptop on for most of the day.
So the problem seems to be really due to 2.6.24. -- Linux kernel 2.6.24-12 lockup https://bugs.launchpad.net/bugs/204996 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
