10 this document explains the stall detector's "splat" format.
13 What Causes RCU CPU Stall Warnings?
16 So your kernel printed an RCU CPU stall warning. The next question is
17 "What caused it?" The following problems can result in RCU CPU stall
37 RCU CPU stall warning messages. Especially if you have added
54 memory, you might see stall-warning messages.
62 CONFIG_PREEMPT_RCU case, you might see stall-warning
