Hi everyone,

I wanted to ask what the current status of Ryzen support is and/or
whether any new changes are planned.

My situation:
* second generation Ryzen: 2600X
* running -CURRENT
* I have done the things described here:
https://lists.freebsd.org/pipermail/freebsd-current/2018-June/069799.html
* no full system freezes, but under load, e.g. building with 12 threads,
programs start to segfault.
* memtest86 ran through without issues
* on a Linux dual boot I haven't had any issues

Is this a known problem? Anythings I can do about it? I thought the
Ryzen problem were only supposed to happen with first generation CPUs...

First gen (R7 1700) here, overclocked to 3.9GHz, also running CURRENT — never had any unexpected segfaults, even when building with 16 threads.

The only bug is that the bottom (chipset) PCIe slot breaks when an NVMe SSD is installed / chipset USB3 ports don't work:
