es_callback() in /sys/pci/es1370.c does not check play_speed,
so an invalid ioctl() causes integer divide fault in kernel mode.

Fix: Here is a temporary patch to avoid this problem.
How-To-Repeat: set 0 as SNDCTL_DSP_SPEED

  speed = 0;
  ioctl(fd, SNDCTL_DSP_SPEED, &speed);

Is this still a problem with the newpcm sources?

This isn't a newpcm problem and hence not Cameron's. I'll deal with feedback.
