Tony Luck at Intel is still maintainer for ia64 but I don't think even he's working full time on it. > Well, since hp is the major customer for Itanium CPUs, it's entirely > plausible after all that hp focuses on hp-ux and thus Intel doesn't > care about Linux on ia64. HP focuses on propietary operating systems that it can maintain by itself and which are now exclusive to Itanium - HP-UX, NonStop and OpenVMS.
