[Sugar-devel] Wanting to know a bit of (NetworkManager) workflow upon resume-from-suspend

[Ajay Garg]

Just an updated version ::


Hi all.

I'll ask this straight ::

"""
Is there an already tested-cum-recommended method, that could disable
mesh-network, both during reboots and resume-from-suspend?
"""

Possible options (not tested by me) ::


a)
A driver,  encapsulating the patch at
http://lists.infradead.org/pipermail/libertas-dev/2007-June/000448.html
(as per http://dev.laptop.org/pub/firmware/libertas/RELEASE_NOTES)


Query : How can I ascertain if this patch is present on a particular XO-1?





b)
(For Reboot) ::
Add the bootstrap script 'echo 0 > "/sys/class/net/eth0/lbs_mesh"' in
'/etc/init.d/NetworkMaanager'.

(For Resume-Upon-Suspend) ::
Add the disable_mesh.sh script (at
http://download.sugarlabs.org/dextrose/testing/dx3/rpms/source/dextrose-platform-2-2.fc14.src.rpm)
in "/etc/powerd/postresume.d".


Query   : While the (For Reboot) case is guaranteed to work stably every
single time, can the same be said about (For Resume-Upon-Suspend) ?
Answer : No. The (Resume-Upon-Suspend) case does not work. So, this
solution is rejected.




c) Any other unknown in-the-dark hack.



Regards,
Ajay
