按照duzhig 介绍的方法 修改相关参数后内核运行情况如下：（运行环境：fc8）

并且skyeye-testsuite-2.3带的linux\at91rm9200里的例子运行也出现同样的问题；而linux\s3c2410下的内核和配置启动正常，可以在启动完毕后输入命令如“ls”参看虚拟机上目录结构.
请大侠们帮我看看，问题在哪哦；谢谢了。

我也遇见这个问题了 好像内核的问题 你可以把
xxx\skyeye-1.2.4\arch\arm\mach\skyeye_mach_at91rm92.c
中的
if(skyeye_uart_read(-1, &buf, 1, &tv, NULL) > 0)
                {
                        int i = 0;
                        for(;i < UART_NUM; i++){
                                /*if( (((io.uart.cr & 0x30) >> 4)) == 0x1 )*/    /* 把这个判断去掉好像就可以了 */
                                {
                                        if(io.uart.imr & AT91RM92_US_RXRDY)
                                        {
                                                io.uart.rhr = (int) buf;
                                                /* Receiver Ready
                                                 * */
                                                io.uart.csr |= AT91RM92_US_RXRDY;
                                                /* pending usart0 interrupt
                                                 * */
                                                io.ipr |= AT91RM92_ID_US(i);
                                        }
                                }
                        }

感谢duzhig的回复;取消那个判断后就正常了.
