>Organization:
>Environment:

	hardware: Panasonic Let's Note CF-A1EV
	OS: FreeBSD 4-stable (July 21, 2000)
	    with newpcm ds1 driver (2000/07/19 14:18:47 PDT)

	kernel message shows:

pci0: <NeoMagic MagicMedia 256AV SVGA controller> at 2.0 irq 10
pcm0: <NeoMagic 256AV> mem 0xfec00000-0xfecfffff,0xfe400000-0xfe7fffff irq 10 at device 2.1 on pci0

>Description:

	previous pcm driver works fine.
	but with current driver, kernel displays:

pcm0: play interrupt timeout, channel dead

	and doesnot play sound.

>How-To-Repeat:

	for example: mpg123 *.mp3

>Fix:

	my poor fix is under this.
	my note PC plays good with this patch.
	please correct this problem.

	ES1371 system plays good without/with this patch.
