Narrative:

Wake turbulence encounter with aircraft [caused] upset approaching 60-degrees left bank. Arriving from south on autopilot; cleared visual approach to follow md-11 from north which was established ILS 27R final approach behind another embraer jet; which slowed prematurely. As we were descending from 3;000 to 2;100 approximately 6 NM from jalto ILS 27R final approach fix on a dog-leg to 27R final and cleared behind md-11 5-miles ahead; encountered wake turbulence; upset up to 60-degree left bank in approximately 1-second. Manually recovered; overriding autopilot; and immediately flying out of wake turbulence. Numerous EICAS faults encountered for autopilot; autothrottle; and probes. Continued hand-flying visual approach to normal landing. All EICAS faults cleared on the ground. Apparently the 50-knot north wind blew the md-11 wake turbulence intact far south of the 27R ILS final rather than the 50-knot wind dissipating wake turbulence. Approach control provided adequate warning our following md-11. We heard approach control slow the md-11 when the preceding embraer jet slowed prematurely ahead of the md-11. We widened our turn to keep distance separation from md-11. The wake turbulence upset was precisely like the recent simulator windshear training in severity and rapidity of roll-rate; except we immediately flew out of the wake turbulence. All passengers and flight attendants were seated with no alarm reported upon questioning lead flight attendant.
