The spec of my machine is this:

- CPU - Celeron 1007u
- 16GB SSD
- 2 GB RAM
(rest as per the above page)

I modified the boot rom to have coreboot + seabios payload so that I can
install a non-chromeos system. It used to happily run Debian but was
locking up occasionally. Perhaps it has a bad RAM or a faulty DDR
initialization in the coreboot.
