Just would like to report that I have almost exactly the same problem (log shows "soft lockup - CPU#0 stuck for 22s!"), with TP-Link TL-WDN4800 WiFi adapter. Apparently someone has exactly the same issue with me at https://forum.level1techs.com/t/solved-linux-is-unstable-ever-since-i-upgraded-to-ryzen/117541/152 .

Not sure if I have other same components with the OP in the level1techs forum. But for me the soft lockup definitely comes from the WiFi driver process (it mentions about ath9k_hw_wait, which is the WiFi driver in kernel I think).

It seems to me that TP-Link TL-WDN4800, with a recent kernel (I tried 4.10, 4.11, 4.13) can reliably re-produce the soft lockup issue within an hour in Ubuntu 16.04. (Of course you will need to turn on WiFi)

I have given my Ryzen CPU to a friend who is a windows user. But I kept a copy of the log - let me know if you guys need me to upload it.
