That "bug" is there for a reason. Get a real compiler, then it will work OK. Compile that kernel with your compiler, your fix in place, and then try to run it on a PIII or later CPU and it will Oops all over the place. Run it on any CPU that supports FXSAVE and it will likely blow chunks (all the Intel CPUs will, but I don't know for sure about the AMD CPUs that support FXSAVE). -- Doug Ledford http://people.redhat.com/dledford Please check my web site for aic7xxx updates/answers before e-mailing me about problems
