AFAICS there's no BUG_ON() or panic() in the RCU code, outside early init code allocation failure paths where we genuinely can't continue.
( Unless it _is_ one of those BUG_ON()s triggering during early resume, reconstructing kernel threads, or the BUG_ON() comes in indirectly via some other way ... )
Dave, one thing that might be worth trying is to disable CONFIG_BUG and see whether the system manages to limp through to get console output?
Thanks,
Ingo
