Yes.

OK, if it's not a regression that's fine with me.
Everything I've done is merged so let me know when you want to merge your changes. I also merged the multiboot v1 patches.

Not sure what you meant. But I've already cherry picked amachronic's patches to my local branch and reported results:

It works for me and adds around 100 bytes to thumb size (119676 without, 119759 with those patches)

I tested bootloader on top of the latest changes - it works. So I think it's ready to be merged.

agreed -- thatd be our smoking gun

--- End quote ---
It's been long time but JFYI. Changing voltage and forcing non HS mode didn't help. What helped - unboosting cpu. Finally found the culprit. Not sure why but with boosted CPU sd writes are pretty fast fail on my e200v2 (only writes, reads are fine - often fails even on bookmark creation). And after cpu_boost(false) gigs are written without any errors.
It's not something sd card specific - I tried two different brands (samsung and sandisk).
