It looks like /sys/module/preprocessor/parameters/max_cstate is not available in Intrepid, at least not in 2.6.27-7-generic. It would be nice to be able to configure max_cstate at run-time. I run ubuntu on my laptop (Lenovo T500) and switch between working in quiet and noisy environments, usually without rebooting (e.g., via suspend). In the quiet environments (like at home), I need to set max_cstate to eliminate annoying whine/crackle due to state C4, and in the noisy environments (on a plane), I prefer longer battery life. It's inconvenient to have to reboot every time I make this transition. To rephrase, does anyone know of a way to alter max_cstate at runtime in 2.6.27?
