We had some issues on cetrain HPsystems with the built-in keyboard emulation being extremely slow, resulting in similar symptoms.How is that going to help /boot?Presumably this is the same problem that affects some Soekris boxes? Or arethey from another vendor?Must be a different vendor, Soekris doesn't have any amd64 products. ISTR that the Soekris problem was that it took ~5 minutes for boot2 to show up, instead of ~5 minutes for the kernel to start.
Yes and on my NET5501 the delay between mbr boot and /boot is still 2 min 10 sec, with mbr and bootxx_ffsv1 built from 5.0_RC2 sources. After that, /boot loads the kernel and runs it with no delay.
The box with the /boot-to-kernel delay is a ASUS P5Q with a Core 2 Quad CPU.
How can I turn on DEBUG for sys/arch/i386/stand/lib/exec.c, which I think where I would start looking?

Which points strongly to the boot loader, since memtestplus doesn't useany part of our kernel.But it might initialise the pckbc the same way NetBSD does in early console setup.
In case it matters, I tested both with and without a keyboard attached to pckbc - no difference.
