Good point. The bios has a number of ways to cause a reset that
coreboot doesn't have. I don't know how many different ways Linux will
attempt a reset. If it always works when you hit the reset button, you
will need to look at the software reset path.

When linux does the reset, is the coreboot output the same? Does it do
the "Resetting the processor"?

A few things you can look at are a memory test prior to the wbind and
you can also try dumping the MC registers to see if they are getting
setup differently on the failing case.
