>Description:
      When I load snd_ich.ko to support my AC97 sound, I have strong CPU usage in interrupt field of "top" (~40%). It was OK when I'd did such on previous (5.4, 5.3) versions, i.e. it's not a my hardware's problem; I'd try to "kldload" old versions of sound.ko or snd_ich.ko form 5.3, but problem is stand still.
