System: NetBSD toblerone.hw.abs.acrys.com 9.99.96 NetBSD 9.99.96 (XEN3_DOM0) #2: Thu May 19 20:42:31 CEST 2022  kardel@pip:/src/NetBSD/cur/src/obj.amd64/sys/arch/amd64/compile/XEN3_DOM0 amd64
Architecture: x86_64
Machine: amd64
>Description:
	Booting XEN3_DOM0 9.99.96 on a Supermicro ends up with a black screen after the Xen boot messages.
	Turns out the vga0 is not attached as it is not configured for XENPV - see XEN3_DOM0.
	#vga*           at pci? dev ? function ?# Needs acpi_md_vbios_reset
						# in acpi_wakeup.c (!xenpv)
	dmesg:
	ppb38 at pci41 dev 0 function 0: ASPEED Technology AST1150 PCIe-to-PCI bridge (rev. 0x04)
	ppb38: PCI Express capability version 2 <PCI-E to PCI/PCI-X Bridge>
	pci42 at ppb38 bus 200
	pci42: i/o space, memory space enabled
	ASPEED Technology ASPEED Graphics Family (VGA display, revision 0x41) at pci42 dev 0 function 0 not configured

	In 9.99.55 vga0 did attach.
	vga0 at pci42 dev 0 function 0: vendor 1a03 product 2000 (rev. 0x41)
	wsdisplay0 at vga0 kbdmux 1: console (80x25, vt100 emulation)

	As these ASPEED VGA/BMC/IPMI devices are in many of the larger servers dropping VGA device support is
	a serious regression.

	Originating PR kern/55667

>How-To-Repeat:
	Boot XEN3_DOM0 9.99.96 on a server with ASPEED VGA graphics. observe a black screen.
>Fix:
	revisit VGA support for XENPV

 As a workaround, one can boot with
 menu=Boot Xen sync:load /netbsd-XEN3_DOM0 ; multiboot /xen-debug.gz dom0_mem=256
 M console=vga sync_console=true vga=text-80x80,keep

 With this xen keeps control of the VGA console and the NetBSD kernel
 can print on it. You don't have keyboard input, but at last you can see
 the boot messages
