PROM console is just slower than anything else for whatever reason.
Even though PROM console drives the same output, using the native CONFIG_SERIAL_SUNHV is much faster and does not generate the timeouts.
That's why I told the original poster to simply disable CONFIG_PROM_CONSOLE, it should never be used. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
