[coreboot] and/or busybox issue with alix2c3 serial console

[ron minnich]

what's usually going on here is that /sbin/init starts and tries (and
fails) to open a console. IIRC there are some hardware checks in the
ttyS0 code that look for bits set "correctly" in the hardware. Another
typical problem is interrupt setup -- there may not be any interrupts.

can you ssh in to the box when it is up? There are lots of simple
tests to try if so.
