Hi,
When pxe boot is performed hundreds times, an error occurs.
error log outputted is "e1000e :probe of 0000:00:19.0 failed with error -3".
linux kernel is using the version 3.11.6 and e1000e driver is using the version
2.5.4.
Using intel QM57 chipset, network is PCH LAN and 82577 GbE PHY.
firmware is Intel Boot Agent GE v1.3.30 Alpha-1.
I tried correction.
add e1000_init_swflag_ich8lan.
