In the commit message to pci.c Stefan wrote 0x40. So one had a 
nice chance to include the define into pcireg.h ;-)

In the meantime Stfan has committed that already.

I'm running 2.2-STABLE and have zero problems at all ! Runs perfectly
stable ! Maybe you should check your kernel config file or upgrade
to 2.2-STABLE and do a make world ???

With the -D option, which allows you to checkout a release branch
or HEAD (-current) at a certain date ...

Just in case that you read the mailing lists and news you might have 
noticed, that Justin worked very hard on that and if you update your
machine to 2.2-STABLE, you'll see, that all the problems will go
away. I have a really rock solid 2.2-STABLE here, no matter if I
do large I/O disk benchmarks, dumps and such !

I'll give you a kernel config file as reference in the attachement.

_The_ open problem ??? Is it a well known problem ? ;-)) Well, I
have _zero_ problems in this area. FreeBSD acts as a Internet gateway
here and I' gettings nearly all mailing-lists, have squid running,
a WWW Server ... and no problems with open.

I suggest you tell your problems more verbously.

But anyway ... there is a STABLE tree, that's RELENG_2_2,
either you cvsup the sources or the cvs repository, if the latter
is the case for you, simply checkout RELENG_2_2

	# cd /somewhere_with_about_150_MB_free_space
	# cvs checkout -r RELENG_2_2 src
	# cd src && time make world >& world.log &

Since you have problems with your SCSI subsystem it's surely a
good idea to build and install a new stable kernel first before
doing a make world.
