I am using the snd_cmi module with a CMedia CMI8738 sound card. The device is recognized: pcm0: <CMedia CMI8738> at io 0xd400 irq 16 kld snd_cmi (1p/1r/0v channels duplex default) However, whenever the driver is used to play any audio, the system will typically hang after a few seconds of play. There is no panic message that I can tell (nothing in syslog), and the system is completely unresponsive. The only way to reboot is to reset the system. How-To-Repeat: # kldload snd_cmi Then use any audio application.

This happens with both the snd_cmi kernel module and with the driver compiled into the kernel. I also tried both debug and performance builds, with the same result. Interestingly, with the system booted in single-user mode the problem does not happen. I will try narrowing it down further. Perhaps it is caused by an interaction between the driver and other kernel modules (which would not be loaded in single-user mode). __________________________________________________ Do You Yahoo!?
