Re: [Xen-devel] [PATCH v2] Fix scheduler crash after s3 resume




But you neglect the fact that waking vCPU-s at this point is
unnecessary anyway (they have nowhere to run on).

Hm, can't they still run on cpu 0? Also, I did earlier try to patch this more primitively by adding a check to vcpu_wake whether the cpu is in cpu_online_map, and whilst it stopped the crashing, I observed some unexpected hangs w/o any serial output - sometimes just the dom0 would hang, sometimes also xen would stop being responsive on serial. So I figured out that these missed vcpu wakes account for something still.
