Interesting that you never came across the much publicised solution to this problem (perhaps your searches were too specific). Try disabling uniprocessor apic, either via a boot time option as suggested by Karol Kozimor, or in the kernel config itself. The kernel config option is CONFIG_X86_UP_APIC Let us know if that works Cheers Andrew ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
