ia64 is good at detecting & recovering from memory uncorrectable errors. x86 is significantly behind, due to historically not being able to recover from uncorrectable memory errors.
ia64 had the Intel defined MCA Spec which defined the interaction between SAL and the kernel. x86 does not have a similar well defined way of how errors should be handled. It would be good to agree on how the errors should be handled.
