Thanks Martin. Very neatly explained !!!! :) I tried the "rmmod/modprobe" hack in "olpc-configure", and it worked (obviously because, this time the "/etc.modprobe.d/libertas.conf" could be fetched/read from persistent storage). Mesh-icons were no more visible in the neighborhood-view (both during reboot, and resume-from-suspend). But I too felt that this is more of a hack, and not a clean solution. So, I ventured out exploring dracut. I created a initramfs image on my home/work laptop, hosting Fedora-14, via the command :: "dracut test.img" and then listed the contents of it "lsinitrd test.img" I saw that "/etc/modprobe.d/*" files were a part of "test.img". So, I think that these files _are_ included as part of the initramfs image, as per say. So, """ Is this observation (that /etc/modprobe.d/* files are included, as per say) in line with what is expected? If yes, that is kind of a relief, since that would mean that only "/etc/modprobe.d/libertas.conf" is not being included (in initramfs that is).

When the laptop needs activation, it loads a different initramfs that among other things loads the libertas module. You need to get your /etc/modprobe.d/ files into the initramfs. For your vanilla build, look into dracut-modules-olpc. If you're hoping to get this integrated into a build with an alternative initramfs (hint: Ceibal) that build will have a custom version of dracut-modules-olpc. That is the right way. When the laptop is in secure mode, olpc.fth is _ignored_, so no chance to set a kernel cmdline there. An easier alternative might be to check for those flags under /sys, and if they are there, rmmod/modprobe libertas for example in olpc-configure (so during early boot). <div class="HOEnZb"><div class="h5"> m -- <a href="mailto:martin.langhoff@gmail.com">martin.langhoff@gmail.com</a> <a href="mailto:martin@laptop.org">martin@laptop.org</a> -- Software Architect - OLPC - ask interesting questions - don't get distracted with shiny stuff - working code first - <a href="http://wiki.laptop.org/go/User:Martinlanghoff" target="_blank">http://wiki.laptop.org/go/User:Martinlanghoff</a> </div></div></blockquote></div>
