available frequency steps: 2.80 GHz, 2.80 GHz, 2.80 GHz, 2.80 GHz, 2.80
GHz, 2.80 GHz, 2.80 GHz, 2.80 GHz, 2.80 GHz, 2.40 GHz

They define 9 2.8 GHz frequency steps and one 2.4 GHz.
That means if OS is going down with speed step by step it will take a
while until you reach 2.4 GHz.
This could be intended (avoid possible performance losses), but also
just be a BIOS bug.

No idea whether it helps, but I would give it a try.

Maybe you find some specs on the Intel site what speed steps should be
supported and how many power/temperature gain you can get. 2.4 GHz
doesn't sound like you save a lot of energy...
