Page fault early in boot

Hello

I tried to boot NetBSD-current (i386 and amd6), BIOS and UEFI modes) on a 
Dell server, it always panic on a "fatal page fault in supervisor mode"
early during the boot. The backtrace says we went there through
main/fork1/lwp_create/memset

A screenshot is available there:

Any idea how to debug that? I expected NetBSD to lack some hardware
support on this recent machine, not to be unable to reach single user 
mode.
