Dell Latitude LS. 

pcm0@pci1:0:1:  class=0x040100 card=0x00801028 chip=0x800510c8 rev=0x20 hdr=0x00
    vendor   = 'Neomagic Corporation'
    device   = 'NM2200 MagicMedia 256AV Audio Device'
    class    = multimedia
    subclass = audio

The problem also exists on 5.x.

>Description:
System locks up hard after probing pcm if enabled.

>How-To-Repeat:
Boot with pcm enabled on a Dell Latitude LS w/ MagicMedia 256AV audio.

>Fix:

commenting out nm_wr(sc, 0x6cc, 0x87, 1); in nm_initcd() stops the hang.
