booting 9.0_RC2 on a Gigabyte server

[Clausen, Jörn <joern.clausen%uni-bielefeld.de@localhost>]

Hi!

We are currently testing some servers with Gigabyte MZ32-AR0 mainboards 
and AMD Epyc 7702 processors. I just tried booting the UEFI image of 
NetBSD 9.0_RC2, but got a panic late in the process, when a USB mouse is 
detected. Here is a screenshot using the board management controller:

and this is when connecting directly to the VGA/USB ports on the 
mainboard (using a Raritan KVM, so I cannot easily disconnect the mouse 
either):

Is there a method to let NetBSD ignore these devices?

Is the UEFI boot image usable over a serial console?
