Public bug reported:
WOL after suspend works only once each reboot. If I suspend the computer after
I woke it once, WOL won't work any more, but bringing it back using the power
button seems to be fine.
I'm using an old Gericom Notebook with a Via Rhine II onboard LAN.
To get WOL to work in the first place I
- edited /etc/init.d/halt (NETDOWN=no)
- added these lines to my /etc.rc.local
ethtool -s eth0 wol g
echo -n ILAN | tee /proc/acpi/wakeup
echo -n PCI0 | tee /proc/acpi/wakeup
- also tried to change some variables in /etc/default/acpi-support:
MODULES_WHITELIST="via_rhine" # addded via_rhine
STOP_SERVICES="networking" # added networking
SKIP_INTERFACES="dummy qemu eth0" # added eth0
After the first wake up using WOL, ethtool and /proc/acpi/wakeup show the same
proper values.
The attached pm-suspend.log and dmesg.log are taken after the following
sequence:
- reboot
- suspend and resume with power-button
- suspend and resume with WOL
- suspend and resume with power-button after trying WOL
Interesting is this line "via-rhine: Woke system up. Reason: Magic packet." in
dmesg. It appears each time when _trying_ to wake the pc with WOL. Thus it
seems the packet is coming through to the ethernet module (via_rhine), but it
can wake up the pc only the first time.
btw: also tried the kernel parameter apm=on apm=power-off with no
effect. For the latest tests and dumps I removed them again.
