The subject version of iceweasel hangs while trying to load the default Google search page. The prior version worked fine. The kernel mutex fix for the pulseaudio issue seems to be valid: my firefox-8 build didn't crash when I clicked on the main pull-down menu (upper-left of the firefox window), which reliably triggered the mutex crash before. I'll try iceweasel again to make sure what I saw wasn't simply a network issue of some kind. --Bob
