This is with Ubuntu 2.6.22-9.25-generic but has likely been a problem for this machine since 2.6.22-8 at least (prior to this, the md/lvm situation caused the system to be unbootable, so I never hit the "sleep" before...). I cannot reproduce it under (single CPU) i386 or amd64 in vmware. I'm going to try booting single CPU locally to see if it has any impact.
