Are there any links or bug reports to track? > ext3 writes to disk every 5 sec iirc, reiserfs writes every 30 seconds, and they are bypassing the kernels buffering mechanism so noflushd has no effect on that timing. laptop-mode (present in kernel 2.4.23 btw) patches ext3 to use the bdflush timings. For reiserfs you need to patch it yourself (I wrote a patch for that if you are interested). laptop-mode is not available for 2.6 kernels yet. > --- Tim Connors <[EMAIL PROTECTED]> wrote: > > On Tue, 6 Jan 2004, Micha Feigin wrote: > > > > > On Mon, Jan 05, 2004 at 01:36:48PM -0800, Mike Mestnik wrote: > > > > I have a dell8900 and I can't seam to get the drive to spin down on > > > > 2.6.0-test9.
