[getting in late on this]

Tomorrow I will have access to a Dell PowerEdge 6500 (4x500MHz) I can use
to capture info or test patches. Or see if the bug reproduces there in the
first place :)

rwatson mumbled something about wanting to determine what triggered the
prior IPI that the panic later trips over.  I'll have to find a sutiable
place to hide that information...
