Re: 2.6.21-rc3-mm2 hangs my opteron during bootup, ACPI?

I went from 2.6.18-rc5-mm1 to 2.6.21-rc3-mm2
The computer now hangs solid during boot, at this point:

Here it stops with a dead keyboard.  No sysrq, it is time for the power 
button.
A 2.6.18-rc5-mm1 boot continues like this:

gameport: Trident 4DWave is pci0000:00:06.0/gameport0, speed 1884kHz

I'll be trying 2.6.20 next, unless adviced otherwise.
