 Hi, 
  
 thanks for your help. It's been four days now, I'd say above average (last 
 was 
 five days) - and no crash yet. I'm going to wait at least until the weekend 
 before naming a winner, but that's already looking pretty good. 
  
 Just to get things right: the machine stopped crashing fatally - I believe 
 with the addition of€€intel_iommu=off. It starts flashing red, logs those 
 errors in kernel buffer, but stays running. I'd like to backtrack that later 
 on, maybe after the weekend, 
 removing all params and seeing where things go. Unless you'd like me to test 
 something else before that. 
  
 Best regards 
 Thorsten
