Another simple approach to trigger such warning is to let __xen_suspend() jumps to smp_resume immediately after smp_suspend, as a test case for suspend cancel. People can observe all vcpus except vcpu0 fall into that warning frequently.

Do you know if this problem has been observed across many versions of Xen or e.g., only after the upgrade to 2.6.18?

Dunno yet. I just found this issue when adding light weight suspend, and softlockup warning jumps out immediately after resuming back to old context. Then I tried manual cpu hotplug with same finding. I'll try an old 2.6.16 version to see whether it happens as comparison.

Thanks, Kevin
