This message also happens very frequently right before a freeze, but not the last time. Sep 17 14:17:20 hildur-laptop pulseaudio[1293]: ratelimit.c: 10 events suppressed The only relevant information i have found is at http://ubuntuforums.org/showthread.php?t=1460809. The proposed solution is to use the propriatary fglxr driver, but I am already using it. I'm not filing this for a specific package since I don't know what package is causing the error. I am suspecting the kernel and drivers for hda- intel though. ** Affects: ubuntu Importance: Undecided Status: New -- hda-intel: IRQ timing workaround is activated for card #1.
