(sorry for the micro updates!)

Forgot to give chipset details (from dmesg):

(failing) R731 is SandyBridge
=================================
smpboot: CPU0: Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz (fam: 06, model: 2a,
stepping: 07)
Performance Events: PEBS fmt1+, 16-deep LBR, SandyBridge events, full-width
counters, Intel PMU driver.
perf_event_intel: PEBS disabled due to CPU errata, please upgrade microcode

(fine) R732 is IvyBridge
=================================
smpboot: CPU0: Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz (fam: 06, model: 3a,
stepping: 09)
TSC deadline timer enabled
Performance Events: PEBS fmt1+, 16-deep LBR, IvyBridge events, full-width
counters, Intel PMU driver.

I'll update microcode and see if that makes any difference...
