I spoke to soon. OK, something has introduced another regression.

Sigh.

Here is the pattern.

You flash. Linux starts to boot. It thinks it finds an ACPI table. It
coughs chunks and dies.

The next time you boot, it hangs in vsm. Oh, yes, and power cycling
does no help.

I just tried leaving it off for one minute and ... it hangs in vsm.

!@#$#@!$#@.

I'm a little concerned that we broke the lar zeroing code again. that
would explain the bogus ACPI bits.

we're breaking things too often. I think we may need to stop
committing until we get a test. So we may need a signoff, "Tested-by",
and no commits until that is seen.
