I should note that 4.2 works fine for me (I haven't cut a CD though) on the Tlaser's at NASA/Ames. This has to do with whether a PCI implementation leaves enough bits at the top of 32 bits for us to store a hose number (dwlpx instance in this case). Sadness. I always knew this was a risk, but hoped we'd squeak by. So, basically, a large number of alphas will not work in 4.X because of the boot issues (which nobody really understands) and the hose stuff.
