Hi! This has started happening on -HEAD recently. No, I don't have any more details yet than "recently." Whenever I get an NMI panic (and getting an NMI is a separate issue, sigh) I get a slew of "failed to stop cpu" messages, and all CPUs enter ddb. This is .. sub-optimal. Has anyone seen this? Does anyone have any ideas? -adrian
