After few test again, I guess its not intel_idle halt the machind. After intel_idle set to build-in the acpi_idle will not loaded, and system halt because acpi_idle is not loaded.
I boot the machine with 2.6.35-18 kernel and try to insert intel_idle.ko. It failed and dmesg told me intel_idle yielded to acpi_idle. I try acpi=off in boot parameter, and system halt. -- Kernel 2.6.35-19 fails to boot Lenovo S10-3 https://bugs.launchpad.net/bugs/634702 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
