So:

On the box which showed problems, I had:

-> CPUID: 306a9  Family: 06  Model: 3A  Stepping: 09  uCodeRev: 00000012

Update done with 

pkg install devcpu-data

service microcode_update start

Now I have:

-> CPUID: 306a9  Family: 06  Model: 3A  Stepping: 09  uCodeRev: 0000001C

On the spare box that shows no sign of trouble:

-> CPUID: 306a9  Family: 06  Model: 3A  Stepping: 09  uCodeRev: 00000019

Hmm.
