Title:
  Micro-freezes when playing sounds and videos

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  There is lag on all my audio and video (Rythmbox, Totem...) every few seconds.
  The problem disappears when I add "noapic" in the kernel parameters.
  I didn't notice any error messages in the system log (syslog...)

  It is a regression because this issue does not exist in previous versions of Ubuntu on this computer :
  Ubuntu 9.04 : ok
  Kubuntu 9.10 : ok
