2.4.16 with es1370 pci

[Wakko Warner <wakko@animx.eu.org>]

Every few days my es1370 sound board quits working.  The same thing happened
with  2.2.20.  There's absolutely no kernel messages when this happens. 
This has happened while playing sound on 2.2.20.  When I attempt to play any
sound, it just stops.  Here's part of an strace:

open("/dev/dsp", O_WRONLY)              = 4
ioctl(4, SNDCTL_DSP_GETBLKSIZE, 0x806ae1c) = 0
ioctl(4, SNDCTL_DSP_RESET, 0)           = 0
ioctl(4, SOUND_PCM_READ_BITS, 0xbffff880) = 0
ioctl(4, SNDCTL_DSP_STEREO, 0xbffff87c) = 0
ioctl(4, SOUND_PCM_READ_RATE, 0xbffff878) = 0
write(4, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 16384) = 16384

The last write just blocks and nothing is played.  This is very annoying and
I have no clue what's going on.

The only thing I can see is the fact it's on IRQ 15 with the usb controller.

I honestly don't know why I'm doing this, as no message I ever post gets
answered.
