标题: 求助了！eth0: Detected Hardware Unit Hang:引起网卡up.down
各位大侠，火热求助了！

现在是每天都会出现两三次，时间集中在白天，目前看到日志都是出现"Unit Hang",以及"Reset adapter unexpectedly"标志后，出现网卡up. down.按照网上的资料都尝试过了，什么关闭acpi, 改网卡buffer,更换最新的官方驱动,硬件做了换网线，换交换机，换协商模式等(强制)。无效啊无效，求助各位帮忙查看一下原因，感谢了。当前网卡版本是e1000e, 3.3.5。最新了，内核版本为2.6.22.

一下是日志打印的错误：

这种情况下找供应商啊，或者不用板载网卡，换PCIE网卡试试
