On: Persistent-memory error handling

[bsder]

The real issue is that a memory error reboots your entire machine.

That probably isn't the right granularity anymore.

A memory error should probably kick off a signal to the application. If the error isn't caught, then it should probably kill the process.

Memory errors should probably not cause a reboot unless they actually hit a kernel page.

This is already possible for ECC RAM:

So even an application can recover from unrecoverable ECC errors.

But it's not feasible to solve this in applications, since there are many scenarios where such storage should simply be transparent.
