Hi, I am experimenting with the pristine 2.6.15.6 kernel on an AMD dual core CPU machine under FC3. The boot seems fine till i get to the point: Freeing unused memory ... "Warning: unable to open initial console". This is the last message, and then nothing ever happens. Maybe this message has nothing to do with the real error, but that is the last information I can grab. Everything works fine with previous kernel 2.6.13.4, except for occasional crashes under high load, which is the reason for the attempt to upgrade. I borrowed the old .config file from 2.6.13.4, and did "make oldconfig", so most of the settings must have remained the same. Then I also did a "make xconfig" just to have a better overview of what new options have appeared. The kernel compiled seemingly without any problems. By the way, when the old 2.6.13.4 kernel is booted up, there is no such warning about the console, and after the "Freeing unused memory" the next lines are: "Red HAT nash version 4.2.15 starting" ... So maybe the problem is somewhere here. Gaspar
