What errors did you get?

This difference makes sense if it is using something like RDTSC to
calibrate. It runs from power on, so will be higher after a reset.

I think the problem may be that RAM is not completely functional.
Decompression needs RAM, and the payload also needs RAM.
Did you try calling the very simple ram_check() function to test your
RAM configuration? And how does the RAM configuration done by
coreboot compare with that done by the factory BIOS?
