Hi, Some RCU stalls are transient and a system is fully capable to recover after that, but we do want Panic after certain amount of GP misses. Current module parameter rcu_cpu_stall_panic only turn on/off Panic, and 1 GP miss will trigger Panic when it is enabled. Plan to add a module parameter for users to fine-tune how many GP misses are allowed before Panic. To save our precious time, a diff has been tested on our systems and it works and solves our problem in transient RCU stall events. Your insights and guidance is highly appreciated. Thanks! Chao
