Description Jiri Dluhos 2008-01-02 13:05:33 UTC

Observed on an Fujitsu-Siemens Esprimo V5505 laptop with Windows/openSUSE 10.3 dual-boot. The laptop has an embedded Intel LAN device.

When Windows are shut down, it puts the LAN device into a kind of off state (probably for conserving power). Then, when Linux is booted afterwards, it is unable to use the LAN device; the r8169 driver says 'link not ready' or 'link down'. I have found no way to re-enable the card except booting back to Windows and enabling the 'WakeOnLan' switch of the card, which causes Windows not to switch off the card.

I think we need a way how to enable the card from Linux, probably automatically, as a common user would be lost - there is no way to find out what happened, the card simply seems nonfunctional.

This is a known issue, but nobody has a real fix for this since nobody has the needed HW specs.
Here is already a knowledge base article for this issue with workarounds:
