Description scorpionmage 2019-05-24 05:20:33 UTC
Installation of FreeBSD-current on a HyperV Gen 2 VM, the release/version is r347896.

After booting up properly, the console input freezes after a random amount of time. This can be if a user is logged in or not. It can be from 5 minutes after being turned on to 3 hours when this happens, it is random.

This freeze also happens if X is started - X starts with xmonad as the mouse does not work in Gen 2 VMs. There is no screensaver installed.

Console output is not affected, currently a "buildworld && buildkernel" is running and it is outputting new lines. But no input is possible.

Remote login using SSH is not affected, it is still possible to login remotely.

Logging in remotely, dmesg does not report anything.

I have noticed this too in my hyper-V FreeBSD-head vm.
Comment 2 Markus Egger 2019-06-27 11:27:03 UTC
Me, too.

- Windows Server 2016 Hypervisor w/ current updates
- FreeBSD 12.0p6 x64 in Gen2 VM

Me too, same diagnostics, in Hyper-V on Windows 10 (build 1803), with FreeBSD image downloaded and installed from scratch, without any configurations.
