As stated in kern/52995 (duplicate pr) and in the photos linked to in
this PR, the kernel panics on efi_getsystbl() when booting on a Mac.
I recompiled a kernel with options DDB_COMMANDONENTER="bt" set & tried
booting it on a white late 2009 Macbook (mentioned in pr 52995).
System panicked as expected and I now have a backtrace.

With the update of gnu-efi this week, I thought I'd try booting today's
daily build to see if anything had changed and it looks like they have.
The system still blows up in efi_getsystbl but now I have a different
message / backtrace.
panic: kernel diagnostic assertion "va < VM_MIN_KERNEL_ADDRESS" failed:

This has been fixed by recent works by nonaka:
- Increase BOOTINFO_MAXSIZE to 16Kib.
http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/arch/x86/include/bootinfo.h#rev1.30
- x86 efiboot: version 1.1.
http://cvsweb.netbsd.org/cgi-bin/cvsweb.cgi/src/sys/arch/i386/stand/efiboot/version#rev1.2
These are already in netbsd-9.
Now, the following machines boot successfully with efiboot:
- MacBookAir5,2 (Ivy Bridge, 13-inch, Mid 2012)
- MacBookAir6,1 (Haswell, 11-inch, Early 2014)
There are still problems in intelfb(4) on these machines.
Fix by myself is coming soon.

Correct linebytes (stride) for intelfb(4), which fixes screen
corruption on the following machines:
- MacBookAir5,2 (Ivy Bridge, 13-inch, Mid 2012)
- MacBookAir6,1 (Haswell, 11-inch, Early 2014)
Now, wsdisplay(4) console as well as intel(4) driver of Xorg
works fine on these machines.
Also there's no side effects found on another machine:
- ThinkPad T480s (Kaby Lake R)
