我现在使用 DM8168 发现SD卡插拔多了 会出现内核崩溃的现象，有时也肯能会再也读不到SD卡了

                kernel BUG at mm/highmem.c:278!

    Luo Yu，

    请问你使用的sd驱动是否为git上最新的？

    请问你哪里一般插拔多少次sd卡就会出现Linux崩溃? 例如插拔10次，20次？请问你插拔sd的时候，是否有sd的读写操作正在运行？请问你每次拔出sd后，linux是否都有自动识别sd卡拔出？

    我使用 Kingmax Class 10 的SD卡，不容易出现问题，但是偶尔会有linux内核崩溃情况，一般超过20此。（使用其他卡，频率会高一些，有的会在20此内）

    插拔的时候，我会df命令，查看挂载情况，没有其他操作

    每次插拔后，都有自动识别SD卡


    请问最新驱动 在哪里可以更新到？

    由于之前 对SD卡操作时 没有使用sync同步，造成一些其他的错误信息，为方便查找问题，重新更新内核错误信息如下：
