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:

各位大侠帮忙给点思路,万分感谢!!
这种情况下找供应商啊,或者不用板载网卡,换PCIE网卡试试
