Using THE SAME disk and kernel, just attaching it to a Gigabyte X399 Aorus Gaming 7 and a Threadripper 2990wx (Bios 11e), i get this:

Using cpus=1 flag or npci=0x2000 doesn't make any difference... Even adding VoodooTSCSyncAMD.kext to SLE and recreating the prelinkedkernel cannot change anything... do I need a patched kernel or a DSDT?
If I try an existing Sierra installation that works for my Ryzen I get an Invalid kernel opcode error and a consequent panic in AppleACPIPlatform.kext.
Finally this is what I get using a freshly created installation pen drive with HighSierraV3Unofficial.dmg:

Please give me some hints... do I need perhaps a similar patch? https://osx86.org/forums/topic/20691-ex ... rk/?page=2
