Hi Jack,
Looks like this problem is not completely gone :( I have seen it now on 2 different machines. On the RELENG_7, ASPM was enabled in the BIOS (INTEL DH55TC MB), so I have disabled that for now to see what happens. On the RELENG_8 machine, its been a LOT better since 7.1.8, but again it happened last night during a backup
