I got several problems with coreboot on X220.
your issues seem very random and unexpected. Three possible explanations come to mind: a) coreboot fails to properly initialize your RAM and this causes general instability. b) your coreboot build is flawed, e.g. some- thing odd in your configuration. c) you flashed the Intel ME Firmware along with coreboot and it's in a bad state.
If you want to further analyze things, please attach your coreboot `.config`.
