I'm using the Patched Openmode PR1.3 kernel - by any chance, does it need to be patched to explicitly enable L2 cache?
Yes, you are correct!

The boot to the Harmattan takes longer than necessary as the stock harmattan kernel (or openmode kernel) do not enable L2 cache in the kexec boot phase. I myself am using a patched "arch/arm/mm/proc-v7.S" which turns the cache back on after kexec().

I guess I should provide the patch for making it boot quicker.
This is the patch from Nemo: https://github.com/nemomobile/kernel...b38e5fe2639e73

BTW, the same also goes with Nitdroid boot, the kernel should also be patched similarily for quicker boot.
