Comment (by cjb):

 {{{
 17:20 <cjb> CosmicPenguin: cool, we're making progress.  doesn't look
       like hardware.
 17:20 <cjb> CosmicPenguin: the ec is strobing the power button line on
       resume, even when we don't resume with the power button
 17:20 <cjb> but the kernel isn't up all the way then
 17:21 <cjb> so perhaps it's being left asserted on the southbridge after
       resume
 17:21 <cjb> and then we don't clear it, and the first time we try to
       read it after resume, which is when an SCI happens, we see a power
       button press waiting.
 17:22 <CosmicPenguin> that would be bad
 17:22 <CosmicPenguin> very bad
 17:23 <CosmicPenguin> We should be clearing it after resume
 17:23 <cjb> why?
 17:23 <CosmicPenguin> but the devils advocate in me said that we
       shouldn't ever be setting it
 17:23 <cjb> yes
 17:23 <cjb> the EC sets it, and there appears to be no reason at all for
       doing so
