floppy+yamaha soundcard => lock

Hi all,

I have problem with soundcard/floppy combination. When I access floppy whole computer locks: doesn't ping, keyboard doesn't work, floppy light shines, but floppy doesn't rotate..., I have to _hard_ reset computer. (It happens at mount, dd on device, cat, ...whatever).

arch: i386 (PII)
soundcard: Yamaha YMF 724 DS-XG
os: OpenBSD 3.2 (also earlier versions do this)

As this is known problem to me, because it occured with linux+alsa driver and was OK with linux+oss and has been fixed since then. The fix in alsa was trivial change of line 122 in file alsa-kernel/pci/ymfpci/ymfpci.c
from:

        legacy_ctrl2 = 0;
to:

        legacy_ctrl2 = 0x0800; /* SMOD = 01 */

As OpenBSD driver of this soundcard is based on alsa documentation, (well, actually borrowed from NetBSD ;-)), I hope the change will be equaly trivial. Unfortunately I'm not a developer and still newbie in OpenBSD world. I just figured that change will be somewhere in files

sys/dev/pci/yds.c
sys/dev/pci/ydsreg.h
sys/dev/pci/ydsvar.h

Could somebody look at it?

Do you need help?
