 Dear Maintainer, 
  
    * What led up to the situation? 
  
 Executing 'composer update' to update a website's software stack or 
 installing 
 a new package with apt, make the system crash with latest kernel version. 
  
    * What exactly did you do (or not do) that was effective (or 
      ineffective)? 
  
 Rebooting and running the previous kernel version. 
  
    * What was the outcome of this action? 
  
 rcu: INFO: rcu-preempt detected stalls on CPUs/tasks: 
 rcu: All QSes seen, last rcu_preempt kthread activity 5252 (4294

    * What outcome did you expect instead? 
  
 No crash.
