I've built my own kernel, but the CPU runs faster (hotter, more fan noise, etc.)
I can't figure out why it's faster. Everything I've checked is the same between the two kernels. If I boot to the Debian provided kernel the CPU runs at 800 MHz, but if I boot to my custom kernel it runs at 1.8 GHz. (These are baseline speeds, after boot without running anything else.) Here's what I've checked so far: * Kernel versions are the same. The Debian version is 3.2.0-4-amd64 and the version I got from kernel.org is 3.2.52. * The boot command line has the same paremeters for both: linux /vmlinuz-3.2.0-4-amd64 root=/dev/mapper/tuzo-root ro quiet * Both boot to the same root file system, and use the same configuration files. * The .config file used to build the custom kernel is the same as the one used to build the Debian kernel. (I'm going to pare it down to just what I need once I figure out this problem.) * Both use the ondemand cpufreq governor. Is there anything else I should check? My next step would be to try and build the kernel source from the Debian package instead of from kernel.org. Maybe this is a code difference? -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
