Bug 20280

Summary: YMF724 initialization fails on my environment.
Product: Base System Reporter: inoue <inoue>

Description inoue 2000-07-29 04:50:01 UTC 
In my system the YMF724 based board (YAMAHA Waveforce 192D) is installed. I tried to make the kernel with the option
device		pcm
but it fails to initialize as follows:

pcm0: <Yamaha DS-1E (YMF724F)> mem 0xed020000-0xed027fff irq 11 at device 9.0 on pci0
pcm0: ac97 codec init failed

Fix: 

In /sys/dev/sound/pci/ds1.c there is the following code:

		if (sc->type == 8)
			DELAY(400000);

When I commented out the 'if' line and increased the delay to 500000, the chip is correctly initialized.
How-To-Repeat: 
In the same hardware environment, make kernel with the above configuration and reboot. It may (or not) occur.
