I can also confirm the updating with proposed updates enabled fixed the shutdown problem on my Asus eee 900.
Slightly off topic (but I see others have sound problem on this thread, which is how I stumbled on it). My sound was still only static / scratchy sounds as before the upgrade. I suspect some config file got trashed when I held the power button to shut down my system during one of the hangs. Marking all alsa and gstreamer packages for reinstall didn't help. FWIW I followed the steps at http://ubuntuforums.org/showthread.php?t=789578 and the static went away but I still had no sound. I ran gstreamer-properties and played with settings and was able to get Test sounds by choosing the ACL662 device rather than default, but still no sound in Rhythmbox. I double-clicked the speaker and with HDA Intel (Alsa mixer) selected as the device toggled the "Headphone" off then back on and plugged in the headphones. Now sound works fine (and switches between speaker and headphones as expected). I haven't rebooted yet but am keeping my finders crossed :-) -- MASTER storing ALSA mixer element values during shutdown hangs nondeterministically due to internal alsa-plugins pulse check https://bugs.launchpad.net/bugs/274995 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
