I've had faulty hardware that was somewhat stable with earlier releases but crashed more often with code from sometime in april; the key point is that the hardware _was_ faulty. memtest86 did not find any RAM errors. 'make build' whilst running stress (from ports) did crash (quickly in the case of the newer OS; after running for a while in the case of the older OS). This was resolved by replacing the CPU with a good one. I guess some people would prefer things to keep running even with faulty hardware. This may be more common amongst people who think that computers crash for no good reason from time to time, though hopefully they are running some other OS...
