I was able to update my BIOS to version 18, but my system still locks up. I tried the following with the new BIOS: - use factory defaults - disable SMT - disable SMT with Typical Current Idle - all of the above with SVM disabled/enabled Right now I set the power supply idle control to "Low ..." and will report back.
On a positive note, I got an error message: Sep 14 13:33:04 user-MS-7B85 kernel: BUG: unable to handle kernel NULL pointer dereference at 0000000000000160 Sep 14 13:33:04 user-MS-7B85 kernel: #PF error: [normal kernel read fault] Sep 14 13:33:04 user-MS-7B85 kernel: PGD 0 P4D 0 Sep 14 13:33:04 user-MS-7B85 kernel: Oops: 0000 [#1] SMP NOPTI Sep 14 13:33:04 user-MS-7B85 kernel: CPU: 6 PID: 1620 Comm: QXcbEventReader Not tainted 5.0.0-27-generic #28~18.04.1-Ubuntu Sep 14 13:33:04 user-MS-7B85 kernel: Hardware name: Micro-Star International Co., Ltd.

We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using latest BIOS available (1.52) We are running Ubuntu 17.04 (amd64), we've tried different kernel version, native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
