 panic: cnopen: no console device

 In a proper boot, it should be:
 wsdisplay0: screen 1 added (default, vt100 emulation)

 That seems strange given that wscons seems to have attached...

 Sorry, but wsdisplay0 is only attached when acpi is disabled (boot 
 /netbsd -2).

 In the case when acpi is enabled, I have acpivga0 attached to acpi0, but 
 the following messages in dmesg:
 agp0 at pchb0: i915-family chipset
 agp0: can't set up chipset flush page: 35
 i915drmkms0 at pci0 dev 2 function 0: vendor 8086 product a011 (rev. 
 0x00)
 DRM error in i915_gmch_probe: failed to set up gmch
 i915drmkms0: unable to attach drm: 5
 vendor 8086 product a012 (miscellaneous display) at pci0 dev 2 function 
 1 not configured
