<div dir="ltr"><div><div><div><div><div>Hello All,<br><br></div>I have an HP laptop that I just re-installed CentOS 6 on. Using the stock 2.6 kernel, 95% of the hardware works. However, if I use a 3.1 kernel, 99% of the hardware works. Almost.<br>
<br></div>With the 3.1 kernel, I cannot start cpuspeed. It cannot write to the file<br><br>/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor<br><br>With the 2.6 kernel, cpuspeed runs just fine.<br><br></div>I'm guessing that the 3.1 kernel provided by elrepo doesn't have the right cpu speed scaling drivers compiled in. Does anyone know how I can tell which driver the 2.6 kernel uses for this, so I can build it for the 3.1 kernel?<br>
<br></div>Thanks!<br></div>-JK<br></div>
