Hey Misc,
Recently I noticed a strange thing on one of my Supermicro X10 servers
and then I reproduced it on a x11 as well.
I even tried and booted a few older bsd.rd like 7.4, 7.6, 7.7 and 7.8.
They all suffer the same issue.
So, what's the problem - if I reset/reboot the BMC device, the iKVM
disconnects and then connects back after the BMC boots. But the keyboard
is not working and here is how the BMC reset looks like from dmesg point
of view:
```

```
Rebooting the OS fixes the problem and the keyboard starts to work after
that.
Does anyone experience similar behavior?

Not sure what happened with `uhub3`.
