I'm not sure if it's related, I have the pulseaudio package installed and noticing that my N900 is crashing when I attempt to surf the web via MicroB or Firefox 1.1 and listen to MP3's via the Media Player. I'm not sure if it's related to pulseaudio as this is my first time trying this since I've purchased my N900 in May. It works for about 3-5 minutes, then it crashes and reboots. The MP3's are stored in the internal (device) memory. Other than that, I do not encounter any other issues with the new pulseaudio package.
