I got a Gigabyte GA-P55M-UD2. When I'm trying to install OpenSolaris 2009.06 it hangs on the exact same line:
EHCI1 is /pci at 0,0/pci1458,5006 at 1d,7 Disable loading of the ehci driver didn't help. In BIOS, disabling both "USB Legacy Function" and "USB Storage Function" helped. (It would be fun to have USB though...) -- This message posted from opensolaris.org
