bus_allloc_resource() in -STABLE sys/pci/if_de.c returning NULL

[Jon Passki]

Hello all,

(if this question is not on topic, please let me know)

I'm attempting to debug an issue and I need some assistance.  I am
running a complicated setup using the following:

--) Mac OS X (Panther) running Virtual PC
--) Etherboot boot1a.bin & bin/tulip.rom Virtual PC disk
--) FreeBSD -STABLE diskless-enabled kernel
--) FreeBSD -STABLE Virtual PC disk

I can boot the FreeBSD VPC disk, with everything working great.  I
can boot the Etherboot VPC disk, which netboots a FreeBSD kernel. 
The kernel loads, but the virtual DEC 21041 (de0) driver fails to
attach.  I've figured this out to be at bus_alloc_resource() within
tulip_pci_attach() in sys/pci/if_de.c.  I'm trying to figure out
what's going on and I want to see the why the attach is failing. 
How should I go about this?

Thanks,

Jon Passki
