The laptop has a SiS 7012 audio chip. Whenever I load snd_ich, the machine instantly uses ~20% cpu power for interrupt handling of irq10:pcm (according to top and systat). Unloading the module brings everything back to normal. This is /dev/sndstat when the snd_ich is loaded: FreeBSD Audio Driver (newpcm) Installed devices: pcm0: at io 0xdc00, 0xd800 irq 10 bufsz 16384 kld snd_ich (1p/1r/0v channels duplex default) pciconf: none1@pci0:2:7: class=3D0x040100 card=3D0x52031584 chip=3D0x70121039 rev=3D= 0xa0 hdr=3D0x00 vendor =3D 'Silicon Integrated Systems (SiS)' device =3D 'SiS7012 PCI Audio Accelerator' class =3D multimedia subclass =3D audio Are there any known problems in snd_ich that I should be aware of?
