Created attachment 290243 attachment-20700-0.html I haven't; and to be honest, I've been procrastinating this issue.
As a very ugly hack/workaround; I've disabled screen power management in xscreensaver: so the CPU keeps drawing graphics on my screen instead of my displays going to sleep. That way, my CPU never really enters the idle states for the crashes to occur. I understand that this is /far/ from a satisfactory solution; but I didn't want to try my luck with the RMA anymore. As long as my system doesn't crash, I can live with this CPU (albeit this continues to frustrate me). I may lose patience in the coming months and go for an RMA anyway. But I'm deterred by the mixed reports for the RMA as well: some people claim that an RMA fixes their issues; some people say it makes no difference. I've even read reports of the RMA'd CPU actually turning out to be worse. I don't think I'm prepared for the gamble. I've been burnt pretty bad with AMD at the moment. For now, I'm just making this work. The next time I'm buying a CPU, I'll do my research more thoroughly and stay away from AMD. AMD did publish an errata in which they claim an issue like this exists; but a solution is ruled out. Which is further bad news. There was some discussion on a fix being at the kernel level, but that isn't anywhere in sight either. I believe these CPU's are plagued by several issues, which probably makes a fix for this at the kernel level hard. However, Windows seems to have managed to fix it. Anyway; rants aside, this is my current take on the CPU.

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. Tested kernel version: native 17.04 kernel 4.10.15 Issues are the same, we're getting random freeze on the machine. Here is kern.log entry when happening : May 10 22:41:56 dev2 kernel: [24366.186246] INFO: rcu_sched detected stalls on CPUs/tasks: May 10 22:41:56 dev2 kernel: [24366.187618] 0-...: (1 GPs behind) idle=49b/1/0 softirq=28561/28563 fqs=913449 May 10 22:41:56 dev2 kernel: [24366.188977] (detected by 12, t=1860207 jiffies, g=10001, c=10000, q=4656) May 10 22:41:56 dev2 kernel: [24366.190344] Task dump for CPU 0: May 10 22:41:56 dev2 kernel: [24366.190345] swapper/0 R running task 0 0 0 0x00000008 May 10 22:41:56 dev2 kernel: [24366.190348] Call Trace: May 10 22:41:56 dev2 kernel: [24366.190354] ? native_safe_halt+0x6/0x10 May 10 22:41:56 dev2 kernel: [24366.190355] ? default_idle+0x20/0xd0 May 10 22:41:56 dev2 kernel: [24366.190358] ? arch_cpu_idle+0xf/0x20 May 10 22:41:56 dev2 kernel: [24366.190360] ? default_idle_call+0x23/0x30 May 10 22:41:56 dev2 kernel: [24366.190362] ? do_idle+0x16f/0x200 May 10 22:41:56 dev2 kernel: [24366.190364] ? cpu_startup_entry+0x71/0x80 May 10 22:41:56 dev2 kernel: [24366.190366] ? rest_init+0x77/0x80 May 10 22:41:56 dev2 kernel: [24366.190368] ? start_kernel+0x464/0x485 May 10 22:41:56 dev2 kernel: [24366.190369] ? early_idt_handler_array+0x120/0x120 May 10 22:41:56 dev2 kernel: [24366.190371] ? x86_64_start_reservations+0x24/0x26 May 10 22:41:56 dev2 kernel: [24366.190372] ? x86_64_start_kernel+0x14d/0x170 May 10 22:41:56 dev2 kernel: [24366.190373] ? start_cpu+0x14/0x14 May 10 22:44:56 dev2 kernel: [24546.188093] INFO: rcu_sched detected stalls on CPUs/tasks: May 10 22:44:56 dev2 kernel: [24546.189461] 0-...: (1 GPs behind) idle=49b/1/0 softirq=28561/28563 fqs=935027 May 10 22:44:56 dev2 kernel: [24546.190823] (detected by 14, t=1905212 jiffies, g=10001, c=10000, q=4740) May 10 22:44:56 dev2 kernel: [24546.192191] Task dump for CPU 0: May 10 22:44:56 dev2 kernel: [24546.192192] swapper/0 R running task 0 0 0 0x00000008 May 10 22:44:56 dev2 kernel: [24546.192195] Call Trace: May 10 22:44:56 dev2 kernel: [24546.192199] ? native_safe_halt+0x6/0x10 May 10 22:44:56 dev2 kernel: [24546.192201] ? default_idle+0x20/0xd0 May 10 22:44:56 dev2 kernel: [24546.192203] ? arch_cpu_idle+0xf/0x20 May 10 22:44:56 dev2 kernel: [24546.192204] ? default_idle_call+0x23/0x30 May 10 22:44:56 dev2 kernel: [24546.192206] ? do_idle+0x16f/0x200 May 10 22:44:56 dev2 kernel: [24546.192208] ? cpu_startup_entry+0x71/0x80 May 10 22:44:56 dev2 kernel: [24546.192210] ? rest_init+0x77/0x80 May 10 22:44:56 dev2 kernel: [24546.192211] ? start_kernel+0x464/0x485 May 10 22:44:56 dev2 kernel: [24546.192213] ? early_idt_handler_array+0x120/0x120 May 10 22:44:56 dev2 kernel: [24546.192214] ? x86_64_start_reservations+0x24/0x26 May 10 22:44:56 dev2 kernel: [24546.192215] ? x86_64_start_kernel+0x14d/0x170 May 10 22:44:56 dev2 kernel: [24546.192217] ? start_cpu+0x14/0x14 Depending on the kernel version, we've got NMI watchdog errors related to CPU stuck (mentioning the CPU core id, which is random). Crash is happening randomly, but in general after some hours (3-4h). Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning and waiting for crash... For now, the machine is not "used", at least, it's not CPU stressed...
