In terms of hangs and system crashes, my Ryzen system has been stable since the fix to relocate the shared page. The random segfault problem during parallel builds went away when I RMAed my original, early-build CPU. This commit: r329254 | kib | 2018-02-13 16:31:45 -0800 (Tue, 13 Feb 2018) | 43 lines Ensure memory consistency on COW. Fixed most of the remaining random port build errors that I had. I think the only remaining problem is random build failures of guile-related ports, but I also see these on my FX-8320E, so they are not Ryzen-specific. Pretty much all of my BIOS settings are the defaults. I suspect that the idle hang issues are motherboard and/or BIOS specific. For the record my motherboard is a Gigabyte GA-AX370-Gaming 5. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
