Bug 17634

Summary: Non-deterministic PnP sound device config at boot-time
Product: Base System Reporter: ocl3 <ocl3>
Component: kernAssignee: freebsd-bugs (Nobody) <bugs>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: 4.0-RELEASE   
Hardware: Any   
OS: Any   

Description ocl3 2000-03-28 12:30:00 UTC 
In my previous configuration (w/ 3.4-STABLE) I would use a /boot/kernel.conf
script to do magic to get my soundcard to work. Things seem to be different
in the 4.0 kernel configuration steps (I stumbled upon "options PNPBIOS" 
which is hidden somewhere in the documentation); boot -v reports some PnP
scanning activity, and pnpinfo(8) correctly reports my sound card (as well
as my 'winmodem' which I dont use). My kernel CONFIG file says "device pcm0"
since i'm hoping to use pcm. 

After much hacking I have realized the following:

if i do a boot -c and then do 'visual' and then expand the nodes, it asks
me if I want to save the changes, (no matter if i say 'yes' or no) it 
*correctly* identifies and runs my sound card. I tried it out. There also
seems to be a difference in the way the PnP stuff is being scanned, since
normally there are about 6 lines of "Pnp device failed to report resource
data", whereas if i do the boot -c thing it only has that line twice. 

This seems to be a stupid bug to do with the bootstrapper or something;
I'd rather not try to involve myself in that stuff.

Fix: 

I dont know. I think the code will have to be changed. :(
How-To-Repeat: 
Install a Crystal card.
boot -c, 'visual', expand some of the nodes, quit
at booting it will show your crystal card.

otherwise it wont show your card.

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?

Is there any way you could try this on 4.3-RELEASE?  4.3-RELEASE
represents a year's worth of development beyond 4.0-RELEASE.
