Red Hat Bugzilla – Bug 510693
Unable to use wol (wake on lan) on Marvell Yukon 88E8056 (sky2)
Last modified: 2010-09-06 11:45:07 EDT
Description of problem: I can configure the wol option for my Marvell Yukon 88E8056 (sky2 module): # ethtool -s eth0 wol g # ethtool eth0 | grep -i wake Supports Wake-on: pg Wake-on: g But on shutdown the ethernet card is powered off too (the link led is off) making impossible for the wake on lan to work. Version-Release number of selected component (if applicable): I've used two different sky2 kernel modules: the fedora kernel one and a recompiled one from the last kernel version: # modinfo sky2 filename: /lib/modules/2.6.29.5-191.fc11.x86_64/kernel/drivers/net/sky2.ko version: 1.22 license: GPL author: Stephen Hemminger <shemminger@linux-foundation.org> description: Marvell Yukon 2 Gigabit Ethernet driver srcversion: FC1DA01907B458FFDE30171 # modinfo sky2 filename: /lib/modules/2.6.29.5-191.fc11.x86_64/updates/sky2/sky2.ko version: 1.23 license: GPL author: Stephen Hemminger <shemminger@linux-foundation.org> description: Marvell Yukon 2 Gigabit Ethernet driver srcversion: 9E9002D9E332A1F2E2BFBB9 Steps to Reproduce: 1. ethtool -s eth0 wol g 2. shutdown -h now Actual results: The ethernet card led turns off. Expected results: The ethernet card should remain on (link led on) waiting for a magic packet. Additional info: Marvell Yukon 88E8056 info: 04:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 13) Subsystem: ABIT Computer Corp.

I also read somewhere that this issue might be related to acpi and it should be solved using acpitool -W. Anyway I enabled everything but with no success: # acpitool -w Device S-state Status Sysfs node --------------------------------------- 1. PCI0 S5 enabled no-bus:pci0000:00 2.

For what it might be worth, I'm experiencing the same troubles on Debian's 2.6.30-1, with the integrated nic from an Asus M3A78-T motherboard. I didn't find any WOL options in the bios, though I was suggested to turn on wake on modem ring instead (somewhere over http://ubuntuforums.org/archive/index.php/t-234588.html ). I will try and report; if needed I can help with my hardware (even by installing a minimal Fedora11) if guided.
I had some feedback here: http://bugzilla.kernel.org/show_bug.cgi?id=13764
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
The fix has been found in the upstream bug report: https://bugzilla.kernel.org/show_bug.cgi?id=13764 Can anyone verify, commit, and close?
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
This bug might be fixed in kernel 2.6.34: https://bugzilla.kernel.org/show_bug.cgi?id=13764#c42
I just tested kernel-2.6.34.6-47.fc13.x86_64 and WOL is now working as expected.
