-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I had problems with CFS too. Similar to the one's you describe. Under heavy disk/cpu-load (like emerge and updatedb in parallel) the system was unresponsive. I changed the scheduler back to anticipatory and the problem was gone. Interestingly i also have a thinkpad, X30 in my case. best Thomas fire-eyes wrote: | Andrey Falko wrote: |> On Thu, Mar 6, 2008 at 10:38 PM, fire-eyes <[EMAIL PROTECTED]> wrote: |>> Hello, |>> |>> I'm running gentoo on an IBM Thinkpad T43.
