(Unfortunately) A new use-case has come into effect :: If I boot with "/security/develop.sig" folder in my pendrive, a) mesh-icons are observed in neighborhood-view, both during reboot and resume-from-suspend. b) "/var/log/messages" show the loading of "msh0". However, there are no exceptions/crash-traces therein. c) Also, I see the presence of a folder "/sys/class/net/msh0". However, if there is no "security/develop.sig" file in my pendrive, a) No mesh-icons are seen in neighborhood-view, during reboot or resume-from-suspend (as expected). b) "/var/log/messages" has no mention of "msh0" (as expected). c) There is no folder "/sys/class/net/msh0" (i guess that is what is expected). Is my observation in line with anyone's observation on olpc/sugar? (Note that the issue was reported by UY deployment; and it could be reproduced at our end as well). Kindly reply with comments.

Following are the steps and observations :: a) Booted with mesh-disabled (via "options libertas libertas_disablemesh=1"). b) In Neighborhood-View, "wifi" and three "adhoc" network icons were present. c) Then, I turned wifi-radio off, discarded network history. Now, only three "adhoc" network icons were present in Neighborhood-View. d) After some time, turned wifi-radio on. Now, "wifi" and three "adhoc" network icons could be seen. e) Again, I turned wifi-radio off, discarded network history. Again, only three "adhoc" network icons could be seen in Neighborhood-View. f) Rebooted. g) Only three "adhoc" network icons were seen in Neighborhood-View. h) After some time, turned wifi-radio on. Now, "wifi" and three "adhoc" network icons could be seen in Neighborhood-View. So, it works fine I guess (note that, mesh-icons were NOT seen anytime in the above steps) :) Regards, Ajay <div><div> On Sat, May 5, 2012 at 6:43 PM, Kevin Gordon <<a href="mailto:kgordon420@gmail.com" target="_blank">kgordon420@gmail.com</a>> wrote: > > > On Sat, May 5, 2012 at 6:26 AM, Ajay Garg <<a href="mailto:ajaygargnsit@gmail.com" target="_blank">ajaygargnsit@gmail.com</a>> wrote: >> >> Well, >> >> I tried once again the "Case 2"; and upon resume-from-suspend, the >> icons appeared fine at my end. >> >> So, the problem was at my end. >> So, it seems that nothing needs to be done right now. >> >> If I face the unusual result for "Case 2" again, I will post the >> "/var/log/messages", which may be scrutinized. >> If someone else faces the same, she/he may do the same. >> >> Till that time, I guess nothing needs to be done. > > > Ajay: > > Since you've already installed the patch, could I be lazy and ask you a > favour?
