--- Comment #3 from Frantisek Sumsal (frantisek@xxxxxxxxx) ---
Clarification: the issue seems to appear only on AMD CPUs. I went through
several runs and tests in the "AMD[0] rack" suffer from the soft lockup above,
but the same workload passes on machines from the "Intel[1] rack"

[0] AMD Opteron 63xx class CPU (family: 0x15, model: 0x2, stepping: 0x0)
[1] Intel(R) Xeon(R) CPU E3-1265L V2 @ 2.50GHz (family: 0x6, model: 0x3a,
stepping: 0x9)
