@Schrauber Hello again.
This issue here relates, as you state, to the kernel used by the installer and as we are essentially using an un-modified upstream CentOS installer kernel the only fix / work around is to use a different version of the installer/kernel (hence the reverting to an older version) or finding kernel boot parameters that address the specific difficulty the installer kernel has with this hardware. There are however plans to update the installer again to be based on hopefully CentOS 7.4 in the already linked:
That issue has an existing note to update this forum thread with any progress and I have updated it to reflect the pending CentOS 7.4 release along with it’s ETA:
Lets hope that helps and anything you can do to prove the upstream installer works would also benefit, but it has of course first to be released; unless you fancy trialling any beta releases of the CentOS 7.4 iso’s as they become available.
Otherwise it’s just down to finding a workaround via kernel command line options passed via the initial installer screen.
Thanks for offering to help and hope this has suggested a useful direction.
