Only the architecture specific time keeping code knows if it's reliable or not... anything else shouldn't depend on this (or even use tsc) Greetings, Arjan van de Ven -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com -- Kernelnewbies: Help each other learn about the Linux kernel.
