On host big41's TW, 4.5.0 delay is roughly the same as with hpg33's 4.5.0, while big41's previous kernel-default-4.4.1 has no delay.
Felix, I wonder one thing, could you just check if any of them patch the cpu on boot. If patching occur, a delay will be shown.
What does "patch the cpu on boot" mean? How would I check?
dmesg should contain something like
microcode updated early to revision 0x%x, date = %04x-%02x-%02x\n
204 seconds for Grub's initrd message to clear, 235 seconds to see a shell prompt with 4.5.0 on TW host big 41.
