after updating to a -current/amd64 kernel with
commit 5ba1445273b0f70468889b5dda99d8c1cbfa5e3c

PCI Extended Configuration stuff written by nonaka@:
- Add PCI Extended Configuration Space support into x86.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)
-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
...
a pineview (i915drmkms) desktop panics on boot with
panic: cnopen: no console device
If one attaches a serial console, all is well (but no X).
Working dmesg extracts:

The PCI Extended Configuration commit is huge, so it hard to see where to
look... "No PCH found" seems like a clue...

Workaround is to "boot netbsd -2", so it is a new-acpi problem.

Can you see where the EAGAIN is coming from? from the bus_space_map or
the bus_space_alloc in agp_i810.c... Does retrying help?

I have also the same error with pineview.
I obtain this ACPI Error at the the begining.
This is from the output of boot -v of current of January 15 of 2016. (I
have copied the message from dmesg of next boot, not from serial console.
The boot output
was stored in /var/log/messages, although it couldn't boot).

I copy the full output of the boot (all but crypto messages). There is
other messages about ACPI, but I don't know if they are important.

It is the bus_space_map.
I have tried your suggestion of retrying when EAGAIN error happens and
it didn't help. (I have retried up to 10 times in a row).

The EAGAIN is coming from bus_space_map - with the little patch below
I see:
agp0: Try bus_space_map again
agp0: bus_space_map returned error = 35 (addr = e0000001)
agp0: can't set up chipset flush page: 35
Another work-around is to keep acpi but build a kernel with
options NO_PCI_EXTENDED_CONFIG

I hadn't spotted that Jose had already done that test!
So all that's new is that it is definitely in the NO_PCI_EXTENDED_CONFIG code.

With NO_PCI_EXTENDED_CONFIG:
agp0 at pchb0: i915-family chipset
agp0: AGP_I915_IFPADDR = e0000001 (100000,ffffffff)
agp0: detected 7932k stolen memory
agp0: BAR size 100000 mismatches detected GTT size 40000; trusting BAR
agp0: aperture at 0xd0000000, size 0x10000000
Without NO_PCI_EXTENDED_CONFIG:
acpi0: acpimcfg_map_bus done

agp0 at pchb0: i915-family chipset
agp0: AGP_I915_IFPADDR = e0000001 (100000,ffffffff)
agp0: Try bus_space map again
agp0: bus_space map returned error = 35 (addr = e0000001)
agp0: can't set up chipset flush page: 35
From sys/arch/x86/pci/pci_machdep.c
#if NACPICA > 0 && !defined(NO_PCI_EXTENDED_CONFIG)
acpimcfg_map_bus(self, pba->pba_pc, pba->pba_bus);
#endif
the call to acpimcfg_map_bus causes the outcome to be different
even though the same address was read.
Note that in both cases we see:
MCFG: bus 0-255, address 0x00000000e0000000: no valid region
