Mandriva 2010.0, Gnome 2.28, pulseaudio 0.9.19-7mdv2010.0. With pulseaudio enabled in MCC periodically the hd light will constantly be on for a period of 4 or 5 minutes and system will slow down to a crawl. Also these comments will be in syslog:

I have pulseaudio enabled but have glitch-free mode disabled. Any assistance in troubleshooting this would be appreciated.
