Thank you for updating us. As per the Kernel Team policy, can you test with a mainline kernel build please. Instructions are at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds - this will enable you to be able to test the latest kernel, and if fixed, we can ascertain what needs to be pulled in from that version. Please make sure you get the latest version, and when loading GRUB select that one. After the above is done you can easily go back to a normal system by rebooting, choosing the normal kernel in GRUB, and uninstalling the mainline build. Thank you again.
** Package changed: ubuntu => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Description changed: I have a Lenovo Thinkpad T60. There is a high pitch noise that comes up whenever Ubuntu 8.10 isn't under load. For example while typing this I hear it. Whenever I'm running an update, loading files, or doing something that seems to be more intensive on the system the noise goes away. Maybe it has to do with the CPU clocking up and down? Or a problem with the RAM? I don't think it's the hard drive as the noise definitely isn't coming from where the hard drive is located. The CPU is an Intel Core 2 Duo, and I have heard about people suggesting it's power management, or the max_cstate settings of the CPU. Either way I only hear it in Linux. + + ----------------------------- + + Workaround: + + Adding processor.max_cstate=2 to grub configuration. + + ------------------------------ -- Thinkpad T60 high pitch noise Ubuntu 8.10 under no load https://bugs.launchpad.net/bugs/309493 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
