    Problem with multiple uarts while booting

    We have 3 Uarts (uartlite) in our ppc440 based custom board.
    UL0 is for console and UL1 and UL2 is for data transfer.
    The kernel hangs when it is booting with the interrupt enabled for UL1 andUL2.
    If the interrupts are disabled for both UL1 and UL2 then the kernel boots fine.
    Somebody please come up with some solutions.

    i am including the kernel log when 1)UL1 and UL2 interrupts are enabled and 2)UL1 and UL2 interrupts are disabled.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    Embedded system software. How much $$ are you willing to spend?
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
