I was pointed out in particular to this kernel commit that only landed in early February: "x86/CPU/AMD: Fix Zen SMT topology." It notes in the commit message, "After: a33d331761bc ("x86/CPU/AMD: Fix Bulldozer topology") our SMT scheduling topology for Fam17h systems is broken, because the ThreadId is included in the ApicId when SMT is enabled. So, without further decoding cpu_core_id is unique for each thread rather than the same for threads on the same core. This didn't affect systems with SMT disabled. Make cpu_core_id be what it is defined to be." That mentioned regression was introduced only in January but had been pulled back into stable kernel point releases from Linux 4.6 and newer. This fix for the (Ry)zen SMT topology is in Linux 4.10 and was back-ported to Linux 4.9.10+ for those still riding the 4.9 kernel.
Zna li netko, ima li još kakvih problema na Ryzenu s Linuxom? Još bolje, ako netko ima iskustva iz prve ruke da ih ovdje napiše.
