I was able to duplicate the problem on a debian etch system with an Intel NIC (e100 driver).
These are my results: - WOL works with kernel 2.6.11 with the root partition mounted over nfs. - WOL works with kernel 2.6.18 with the root partition mounted from a local drive. - WOL is broken with kernel 2.6.18 with the root partition mounted over nfs. - WOL works if the machine is turned off before loading the kernel (the e100 NIC driver is built into the kernel) I also found this bug report against the e100 driver: http://bugzilla.kernel.org/show_bug.cgi?id=5149 Summary (some of these points were already made in the previous posts): - It seems that somewhere after kernel version 2.6.11, the e100 driver was modified so that WOL is disabled after initialization and is re-enabled before shutting down. So, even if all the tools report that WOL is enabled when the system is running, this is not the case, since the driver is probably only supplying a cached state and not the real state of the hardware. - On debian etch, when the root is mounted from a local drive, the shutdown scripts seem to be doing the right thing because WOL works. - When the root is mounted over nfs the code path is different and the NIC driver is not correctly shutdown, so WOL never gets re-enabled. Possible solutions/hacks: - Figure out how to properly shut down the driver when the root is mounted over NFS. Maybe somebody more familiar with the init scripts can work on this. (I tried compiling halt from sources like one of the previous posts suggested, but that did not seem to fix my problem.) - Prevent the driver from disabling WOL in the first place. This is a hack but it was the fastest way to fix the issue on my setup. For the e100 driver I just commented out the following line in kernel_source_path/drivers/net/e100.c // config->magic_packet_disable = 0x1; /* 1=off, 0=on */ ____________________________________________________________________________________ Looking for last minute shopping deals?
