While trying to setup elastix 1.5-rc1-64bit i stumbled upon a problem that seemed to be worth mentioning. My testbed is an hp proliant ML115 powered by an amd 64bit opteron. To get to the point the 64 bit rc1 will not run anaconda and it can not proceed to the actual installation. Console reports do not indicate anything other than the usual Code: WARNING: Graphical installation not available... Starting text mode. And after that it just halts . Not freeze, just stays there displaying a blue screen (bad memories) doing nothing more. 32bit rc1 as well as stable 1.3 sets up fine. Just a quick note: at boot the distro loads sata_nv driver (if it matters). Does any of the above ring a bell to anyone ?
