<div dir="ltr">Hi,<br><br>I have a HP dc7900 workstation which has an Intel 82567LM NIC. BIOS is fully updated.

</div>Awesome! I use it *all* the time with the 10+ machines I use in my<br>
house running Ubuntu server. It saves me many dollars per month, when<br>
these machines are idle.<br>

</div>Please file a bug against the pm-utils package in Ubuntu. Please<br>
explain a bit more there about what the effect is, what hardware you<br>
have, etc.<br>

</div>What are you using to suspend both? /usr/sbin/pm-suspend?<br>
<br>
Can you wake it correctly with other mechanisms besides WoL? Like<br>
just pressing the power button? If so, then it's probably breakage in<br>
the ethernet driver, and may be work-around-able (sp?) with ethtool.<br>
