I have no debugging help to provide but can describe a similar experience. I only tried a direct-boot of FreeBSD once and it may be a long time before I try again. With a Ryzen Threadripper 1950X that normally runs FreeBSD 12.0-CURRENT builds under Windows 10 Pro's Hyper-V, I once tried to boot and use the system directly with FreeBSD --from the same media that it runs on via Hyper-V. (Under Hyper-V FreeBSD runs fine.) It booted. But not too long later it hung up. As I remember I was able to hold a power button in for a longer than normal time to cut the power. If I remember right, the light normally visible on the USB keyboard when it is operational on USB was out after the hangup (and before the forced power-off). As I remember, the video display stayed (but did not update). Ethernet access stopped. The Ryzen Threadripper 1950X does not have the CPU problem that lower end Ryzen's have had. (So for this is confirmed in my testing, contrasted to my earlier access to a 1800X, also used under Hyper-V, but never directly booted.) So, I doubt that CPU issue is involved in the hangup that I got. I will note that I've seen list messages from folks indicating some Ryzen variant for some system --and they were not reporting such hangups, nor did they indicate running under any hypervisors. So, something more local-context-special seems to be involved. === Mark Millard markmi at dsl-only.net _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
