I have a similar problem when I have a 4k sector NVMe drive installed. I suspect in my case it is a Dell firmware bug but not sure. It hangs for me when tearing down UEFI stuff before jumping to kernel. To rule out issues with the EFI system partition itself you could install a /EFI/NetBSD/boot.cfg to instruct bootx64.efi to load the kernel from hd1a:netbsd or whatever your FFS partition is named. -Tobias
