With the Intel issues exposed in meltdown, we were looking at possibly deploying some Ryzen based servers for FreeBSD. We got a pair of ASUS PRIME X370-PRO and CPU: AMD Ryzen 5 1600X Six-Core Processor (3593.34-MHz K8-class CPU) Origin="AuthenticAMD" Id=0x800f11 Family=0x17 Model=0x1 Stepping=1 Everything is at its default in the BIOS, no overclocking etc. However, we are seeing random lockups on both boxes. It doesnt seem to correspond with load/activity. And its a hard lockup. Keyboard not responsive and I cant break to serial debugger, so it doesnt seem to be an issue with something in the kernel going into deadlock. It sort of feels like a hardware issue, but it seems odd that both boxes are showing the same issue with random lockups like that. It could be twice in a day or once every 3 days. Anyone have any insights ? Anyone have any suggestions about better motherboards out there ? We are waiting for Supermicro's Epyc availability, but nothing yet. It would be nice if we could find a board with at least some hardware watchdog on it. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
