The oops looks related with mmap.  Maybe alpha doesn't support the
mmap of coherent DMA pages like intel architectures allow?

Try to disable mmap support in the driver once - e.g. comment out
SNDRV_PCM_INFO_MMAP in struct snd_pcm_hardware.info fields found in
ice1724.c.  Then run aplay with -Dhw option (the default would take
mmap) and give the WAV file the hardware supports (32bit-LE 2ch or
more).

If this works, we can add some workarounds in the ALSA PCM core
routine for mmap.
