BTW, given it hangs during resume, it isn't easy to collect debug info, and there should have been lots useful info there. You mentioned that you can reproduce it on QEMU, could you share the exact raid10 setting? such as which disks behind the raid10. Or can you reproduce the issue without raid10 involved? I will try to reproduce it in my VM if you may provide the above info. Thanks, Ming
