RE: PROBLEM: lk 4.5 oops on boot with Xeon D-1520

[Liang, Kan]

I have no idea why the original email was redirected to Junk folder.
Sorry for the late response. 

I extended BDX-DE uncore code to support BDX-EP. So they share
the same code path. But there is no sbox in BDX-DE.
I once tried the BDX-EP patch on my BDX-DE, it boots fine.
But it looks it doesn't work well for all machines. :(

Could you please try the patch as below? It specially handles the
BDX-DE by removing SBOX support.

Thanks,
Kan
