Last week on the call I reported three of the "installcheck" tests were timing out on s390. In all cases the expect scripts were using a 30sec time out values. Looking at the times reported by stap it appears that 30 seconds is just not enough for the s390. In all cases "Pass 4: compiled C into.." used most or all of the 30 sec. Unfortunately it is not saying much for the speed of the s390 CPUs, but that is not the strong point of the s390 :). To be honest the system I am using is 3000 miles away and I have no idea how current it is. According to /proc/cpuinfo bogomips per cpu: 614.40. Below is the results of my testing. I have attached a patch to increase the timeouts from 30 sec to 60 sec. for the affected tests.
