When I tried to boot 11.1 (or) 11.2 in that, I needed the following tunables to be set from loader prompt to get it booted (otherwise machine reboots continuously). hw.usb.xhci.msi=0 hw.usb.xhci.msix=0 hw.pci.enable_msi=0 hw.pci.enable_msix=0 But, when I tried with 12.0 - ALPHA4, I could able to get it booted without any tunables. So, has anything changed significantly on PCI MSI/MSI-X path? Note: I have a forum topic with my observations about the issue on 11.1/11.2 in the following thread https://forums.freebsd.org/threads/freebsd-11-1-installation-fails-and-rebooting.65814/ Let me know if you need any details.
