[gutsy] Segfault when returning from suspend

[Scott Robinson]

Binary package hint: network-manager

When I return from suspend, this often happens:

please test the network-manager packages available in my ppa ( http://ppa.launchpad.net/asac/ubuntu/pool/main/n/network-manager/) ... the version to test is 0.6.5-0ubuntu16~ppa1

Thanks,

... and please attach your full /var/log/syslog

Also happens here with ipw2200. Will try the above packages (0.6.5-0ubuntu16~ppa1) and report.

For me NetworkManager is spinning in an infinite loop due to segfault.

BTW a workaround when it happens:

  kill -9 NetworkManager_pid
  sudo NetworkManager

Which seems to bring it back ok.

latest is 0.6.5-0ubuntu16~ppa3 ... if you haven't tested ppa1 already, please test that package.

I installed ppa3. Removing graceful termination seems to have helped the situation.

[Aaron Straus (aaron-merfinllc)]

Much better here as well. I haven't seen the problem in a few suspend/resume cycles. I'll let you know if it pops again. Thanks!

[Aaron Straus (aaron-merfinllc)]

Hmm. Ok it happened once for me in many suspend/resume cycles. :(

So it's seems less frequent with these patches but still happens.

My syslog attached. Seems to have crashed before the suspend!
