TI中文支持网我的内核是 Linux-2.6.18_pro500-davinci_IPNC ，用的dm368， 录像一段时间后，一般两个小时，我用的12M码流，换了6M的码流也会，崩溃后打印一大片，1、插入U盘后，也会打印一大片内核错误信息，具体打印在附件里，但是系统还是运行正常，再次插拔U盘后内核就完全识别不到U盘了，2、或者此时访问u盘，ls 下挂载目录，也会打印，一大片，此时再次ls，ls就会挂起，终端无法输入命令，无法停止这个命令， 但是用telnet还可以登录正常， 请麻烦专家给我分析下。

Chris Meng：
Li Qiankun，
请问你是录像到本地u盘上，还是网传码流? 如果是前者，usb是否有disable edma?
是否有尝试过降低DDR的频率，看是否有改善？

回复 Chris Meng:
我们是本地的，u盘和硬盘（usb转sata）都会出现，usb已经禁止了dma，但是实验没有降低ddr频率。下面是我内核启动的信息，感谢你的回答。这个问题困惑了几天了。
