"It happens really rare but in this case... "
- Not that rare for Intel. A few years back I sunk a ton of money into some servers and bought a copy of the latest Microsoft server O.S. The servers were single processor but could be expanded to dual processor which I needed for the workload. After installing the second (INTEL) processor I noticed it wasn't being detected by the O.S. Turns out it was a faulty "look aside buffer" on the Intel processors.
Intels advice? "Repurchase an entirely new system with our next version of processors that's coming out. Maybe that will work"
...And they wonder why Qualcomm and ARM are just obliterating them.
