Then, I'm writing this message. |if (p[0] == 0) |/* No change, try again in a while */ |return; What does this path mean? This path meant umass dev was none, I thought. So reflexible loop occurs until umass device is recognized. If so, I'd like a option to bypass this path when something is set as the kernel param or anything else. which makes the smooth boot process without umass devs. Any idea or suggestion? Eitarou P.S.
