Hi all,

From: Vladimir Kushnir <vkushnir@alfacom.net>
Date: Wed, 16 Apr 2003 00:27:15 +0300 (EEST)
::pcm0: <Yamaha DS-1E (YMF724F)> mem 0xeb000000-0 xeb007fff irq 10 at device
::16.0 on pci0
::ds1: setmap (502000, 1000), nseg=0, error=27
::pcm0: pcs=120, rcs=16, ecs=16, ws=0, memsz=1584 4
::pcm0: unable to initialize the card
::device_probe_and_attach: pcm0 attac returned 6

I also get similar problem, here too.
dmesg NG:
pcm0: <Yamaha DS-1E (YMF744)> port 0xfc8c-0xfc8f,0xfcc0-0xfcff mem 0xfedf8000-0xfedfffff irq 9 at device 9.0 on pci0
pcm0: pcs=120, rcs=16, ecs=16, ws=0, memsz=15844
pcm0: unable to initialize the card
device_probe_and_attach: pcm0 attach returned 6

dmesg OK:
pcm0: <Yamaha DS-1E (YMF744)> port 0xfc8c-0xfc8f,0xfcc0-0xfcff mem 0xfedf8000-0xfedfffff irq 9 at device 9.0 on pci0
pcm0: <Asahi Kasei AK4543 AC97 Codec>

 
I have tracked down that, problem started with rev 1.41 of
src/sys/i386/i386/busdma_machdep.c and still happens with rev 1.43.
If I go back to rev 1.40, the problem goes a way.

Hope this helps,
 Haro
