Panic when trying to boot 10.0_RC3 on a Dell Precision 3660

Hi! there.

Just tried to boot NetBSD 10.0_RC3 on a Dell Precision 3660 workstation 
from amd64 ISO image burned in a DVD-RW.

Got the following panic error (transcribed - so there can be errors):

	boot device: <unknown>
	root device: panic: usbd_transfer: not done
	cpu0: Begin traceback...
	vpanic() at netbsd:vpanic+0x183
	panic() at netbsd:panic+0x3c

	curlwp 0xfffff2ad821f3500 pid 0.300 lowest kstack 0xffff8e042bcb3

I can provide more information if needed.

FYI, NetBSD 9.3 doesnt panics like that, but stops at the "root device" prompt.

Is there anything I can do?

I'd be happy to help support such hardware, not sure how I can help, though.

Thanks!
