That's exactly the case: GENERIC *has* 15 sec delay and doesn't boot either.
And just to mention it explicitly: 4.4-PRERELEASE didn't have these problems, 
it first appeared (on my machine: Duron800, EpoX 8KTA2, 256MB RAM, 2x LSILogic 
SCSI Controllers (U + UW), several SCSI Disks, Tapes, CD-Roms, CD-RWs, 'vinum' 
RAID5) with 4.4-RC1 and was still evident on Sunday, Aug. 19th. Actually, I'm 
running that 4.4-PRERELEASE kernel(.old), until the sky clears up again...

And to be sure, I deleted my whole /usr/obj and did a complete new build of 
world and kernel.GENERIC (at first), but that didn't solve anything...
And I cannot report anything further, because there's no panic, no message, the
machine simply stops. i.e. freezes (?, NumLock still switches the LED, so NMIs
seem to pass).

Ciao/BSD -
Matthias
