I'm running Debian kernel 2.6.8-powerpc, on a 1998 PowerBook G3 Series "Wallstreet / PDQ."
I've been trying to figure out why the hard drive would spin constantly, regardless of what I do with the laptop-mode.conf settings. Based on advice I read somewhere I installed metalog, removed sysklogd and klogd, put the noatime parameter in /etc/fstab, and tweaked my pbbuttonsd & laptop-mode settings. Even after all that, the drive never spun down AT ALL. At some point I manually restarted /etc/init.d/laptop-mode, and after a delay, the drive spun down. SO on a whim I changed the order they start up in /etc/rc2.d by renaming S20laptop-mode to S21laptop-mode. This makes S20pbbuttonsd start first and THEN S21laptop-mode. Now my drive spins down! Great! Except I don't understand why... it seems like the loading order should be the other way around. I've also noticed that it doesn't seem to matter what spindown values I put into laptop-mode.conf -- I have to manually set hdparm -S to adjust the default spindown time. I have it working better now, but I'd like to be sure I have it right. Could another script or daemon override laptop-mode settings, or do I have something broken? Furthermore, I have apm_emu in /etc/modules and lsmod says something is using it, though I was under the impression that pbbuttonsd does not need it. What is using it? [I started to attach the contents of my /etc/rc2.d/ directory, output from lsmod, and the contents of /etc/modules, /etc/laptop-mode/laptop-mode.conf, and /etc/pbbuttonsd.conf -- but I decided I would hold off on the listings until someone asked for something more specific!]
