11.10 works without any problem with card and devices connected. disco-desktop-amd64.iso Ubuntu 19.4 hangs like Ubuntu 18.4 in the same manner. It must be something in xhci-pci.c driver broken. It is important to me and should be avoided by: 1) skipping error when it can't be resolved during boot (it shouldn't prevent Ubuntu 18.4-19.4 system load) 2) the xhci should be "unbuged" besouse it is workable in 11.10.

There are no devices connected to PCI USB card during boot. The desktop Ubuntu 18.04 kernel 4.15.0-46-generic freezes with this card during boot (see attached "photo log" with boot and grub options). I can't access/login Ubuntu or console. It was checked and confirmed on ubuntu-18.04.1-desktop-amd64.iso LIVE CD desktop (with acpi=off option too). Previously I was used and removed USB 3.0 NEC Renesas upd720200 PCI card [1033:0194], which was partially workable under my installation of Ubuntu 18.04 and Windows. It had problems from time to time with FW load from card on start and not detecting USB devices connected even if FW present. I tried and also removed USB 3.0 NEC Renesas upd720202 PCI card [1912:0015] which also was partially workable in the same way (other card bios and newer NEC chip). System was fully bootable with NEC cards. The Etron EJ168 works superb on Windows OS's with directly or with hub connections with USB devices. I can assist in any way to solve this bug as IT Professional.
