我们现在在用imx6 DQ在开发产品，使用的kernel是3.0.35版本的LTIB4.0.0.在测试产品的时候发现，在长时间（3-4天）的进行media播放之后会出现随机性的crash，部分log如下：

楼主你好，你这里使用LTIB还有BSP使用3.0.35版本的话，建议你使用L3.0.35_4.1.0_130816_source这个版本的BSP，它是相对于L3.0.35_4.0.0有更新和改进的。

如果换做是L3.0.35_4.1.0_130816_source的版本的BSP的话再联系我们。

方便提供一下L3.0.35_4.1.0_130816_source的版本的BSP吗？

你好，我现在上传有问题，估计是公司网络的问题。这样晚上我回家给你传，到时候把链接贴给你哈。
