Description Anchor Systems Managed Hosting 2008-04-08 03:15:19 EDT
Description of problem:

Wake on LAN was working on my workstation (used to run backup jobs) on F8 for
the last couple of months. It stopped working recently. It was last working
with 2.6.24.3-50.fc8 (i686) according to my last logs. An improper shutdown
from f9 Beta may have triggered the problem or the upgrade to the latest F8
kernel.

Shutdown from                     WOL works
Power supply disconnected         Yes
2.6.24.3-50.fc8                   No
2.6.24.4-64.fc8                   No
Fedora 9 kernel                   Yes

Version-Release number of selected component (if applicable):
2.6.24.4-64.fc8

How reproducible:
100%

Steps to Reproduce:
1. Shutdown from F8
2. Send Wake on LAN "magic" packet
  
Actual results:
Machine does not power on.

Expected results:
Machine to power on.

Additional info:

05:08.0 Ethernet controller: Intel Corporation 82801G (ICH7 Family) LAN
Controller (rev 01)
        Subsystem: Intel Corporation DeskTop Board D945GTP
        Flags: bus master, medium devsel, latency 32, IRQ 22
        Memory at 4d000000 (32-bit, non-prefetchable) [size=4K]
        I/O ports at 1080 [size=64]
        Capabilities: [dc] Power Management version 2
        Kernel driver in use: e100
        Kernel modules: e100

I rebuilt the kernel from the src RPM, but with e100.c (sha1
3790acc25249d64c2b37fb3304d044cb1077b146) from Linus's git tree.

Wake on LAN now works.

The switch to the 2.6.25 kernel in F8 fixed the problem.
