I don’t know.
When running the installer it does the multiplath for sda/sdb but doesn’t get past those 2 lines to the next part about leaving the multipath as that is when the screen normally goes from basic to GUI sized.
During O/S boot, it brings up the details about the fact that there is no sys-usb so all USBs are exposed to Dom0, then it freezes because that is when it normally goes to higher graphics mode.
This is why I hadn’t upgraded since 4.2.0-RC4, but the person in my other post, when I was asking for help with passing a webcam through to a guest, said I needed to upgrade to get any help.

So it could be related, but I don’t get the blank screen with flashing cursor, I do have text on the screen, but not a fully initialised higher graphics mode.
