Re: Ubuntu Karmic cdma modem problem

[Michael Butash <michael butash net>]

Hi Alexander,

It seems the nightly change you made didn't fix the problem of it not
wanting to put a default route as it still persists.  It did clean up
the proxy-arp log errors, but apparently it wasn't directly related.
Thanks for your efforts regardless!

Here's a complete syslog transaction of the process, I'm not seeing
anything more verbose past it hanging at stage 4 and eventually I
disconnected.  I included some of the transaction from disabling
wireless to go to cdma because I saw a log entry about an NM error
deleting a route, that not sure if there's a systemic issue preventing
the default route for cdma.
