I see. But is 'make sync' actually useful for you? Can you run kvm-ia64 on top of 2.6.24, which doesn't include your ia64 core API changes? Note you will also need to add preempt notifier emulation for older kernels. -- Any sufficiently difficult bug is indistinguishable from a feature. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
