Kernel crashes in __migration_entry_wait

Hi all,
A X86_64 server repeatedly dumps once a while with the following signature:

It seems that this is a bug. I'm not sure if it has been identified and removed, but it cannot be found on the web. The customer was adviced to disable numa balancing to work around and I'm waiting for the latest results from them.

Thank you all!
