That, and if you find the problem driver, you can just disable it individually. example: hint.p4tcc.0.disabled="1" If that doesn't work, try disabling acpi_throttle the same way. Figuring out which cpufreq drivers are attached on your system would be a good start (dmesg | grep cpu). All other cpufreq drivers will continue to function just fine. That's why the title of this message is misleading. cpufreq is a framework, not a single driver. It's like saying "PCI makes my system hang". -- Nate
