Problems within ich driver does exist since eon (especially the DMA
part). It was hidden until the recent improvement against the upper
layer which trying to promote loud failure in case a bug within
specific driver is triggered.

My suggestions:
1) Enable full debugging support (INVARIANTS, WITNESS, DIAGNOSTIC)
2) Don't compile the driver within kernel, use the module instead.
3) Don't load the module during boot. Do it manually *after* finish
   booting (kldload sound ; kldload snd_ich)
4) I need your pciconf -lv ;)

In case all above failed, try to revert your ich.c to revision 1.53 .
