I guess it's pretty flaky :( But still I see some (slow) progress ;) It really could be related to the USB ports on your PC .. if for some reason your PC is not happy with the power-state changes demanded by the Freerunner, then it will reset the USB hard layer, and this has the effect that your internal USB GUID changes, confusing the usb- ethernet driver, and thus giving you inconsistent services. If its at all possible, try running some sort of USB diagnostic app on your PC while this is all going on or check your log files for USB-related messages in the meantime .. ; -- Jay Vaughan ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I don't believe so, as I've not had these issues with 2007.7, but it would be running from flash, whereas I have the problems with 2008.8 running from SD... maybe that's why ? Thanks anyway.

Notice that I'm running 2008.8 from SD so that may change some behaviour vs running it from flash, explaining the network problems. Anyway, it seems it's rather unstable in the first times the system is brought up, and stabilizes after a while. If I unplug the USB cable when I lose IP connectivity, and replug after 1/2 seconds, then it becomes more stable. Well maybe the fact that I'm running a ping 192.168.0.202 continously helps also at that stage : it may help maintain connectivity somehow ? Anyway, I guess I'll be able to test 2008.8 from flash soon, and may be able to tell if that's better. In the meantime, 'screen -R -D' is my friend ;) Hope this helps.

This is also quite compatible with the idea the issue is around ip allocation on Freerunner side: when you remove and replug you will be doing something radical on the usb0 on Freerunner side (I guess the semantic is link down / link up, and logical usb0 network device stays there the whole while). But still then whatever deals with IP allocation can be triggered to reapply static IP or do DHCP request, etc and make the issue go away. | Anyway, I guess I'll be able to test 2008.8 from flash soon, and may | be able to tell if that's better. | | In the meantime, 'screen -R -D' is my friend ;) | | Hope this helps.
