Hmm, can you get devinfo -r output from a working kernel with ichwd loaded?
You might be able to just build the kernel with 'nooptions NEW_PCIB'.
I believe that I've got a similar problem with amdsbwd(4).
It needs some resources (I/O ports) that belong to ACPI.
The problem is that the driver attaches to isa bus which is under
isab->pci->pcib and those particular resources are not assigned to the Host-PCI
bridge.
I think that you already made a suggestion that perhaps isa bus should directly
attach to acpi bus when acpi is available. Not sure if there are any
alternative approaches.
Can you try this:
Not so much. :) the first and last patches I can apply to HEAD by hand,
but /sys/dev/acpica/acpi_pcib_acpi.c is only 387 lines long, so I'm not
even sure where to start.
$ svn cat svn://svn.freebsd.org/base/head/sys/dev/acpica/acpi_pcib_acpi.c | wc -l
531
No difference here on ICH9, ichwd(4) still doesn't attach.
