Standard kernel does not work on Centrino but i586-1GB or i686-4GB kernels do
The standard kernel now has NX (no-execute) support enabled by default. NX requires PAE (Physical Address Extension) support, which should be available on all i686 processors, and is required for accessing memory above 4GB. Unfortunately PAE support is broken on the Dothan (Centrino) CPU (See the errata part of http://download.intel.com/design/mobile/SPECUPDT/30220907.pdf)(...) and no fix nor workaround is planned by Intel. If you have a Centrino CPU, you should use a kernel which doesn't require PAE support, thus you have to use i686-4GB or i586-1GB kernels. This also means that Centrino users cannot have the advantages of NX (on any operating system). The installer has been updated, and should install a suitable kernel (ie i686-up-4GB) by default.
