大家好，
在dm3730中，我集成了ti提供的h264算法库，算法开启正常运行一段时间后，串口端返回了以下错误：
omap3isp omap3isp: isp_wait: wait is too much
omap3isp omap3isp: ccdc 1 won't become idle!
然后算法处理就卡死了，但是程序并没有退出，而是变成了S状态，cpu占用率为0；
接着我重启设备，显示屏显示一片白屏，串口中出现以下错误：
Unable to handle kernel paging request at virtual address ffffffff pgd = cfbe0000 [ffffffff] *pgd=806ff021, *pte=00000000, *ppte=00000000 Internal error: Oops: 817 [#1] last sysfs file:
