Re: i386 GENERIC_PAE panics (i915drmkms related?)
I see similar behavior on NetBSD/i386-7.1_RC1 except instead of panicking,
it just hangs. If console is VGA, one can break into DDB with Ctrl-Alt-Esc.
If console is serial port, sending BREAK does not drop into DDB.
Partial dmesg captured from serial console:

As with -current, disabling "i915drmkms" via userconf (either through
"boot -c" or "userconf=disable i915drmkms" in "/boot.cfg") avoids the
hang.
