Is it a clean or fast shutdown, most distributions mark network devices as down on shutdown, but if the distribution does something stupid like remove the driver module, then the driver is unable to setup Wake On Lan. The wake on lan setup is done in one place in the driver, add a printk to see if it is ever called. I only tried wake from shutdown (poweroff), and like i wrote, on the same system with kernel 2.6.23.12 (nothing changed but vmlinuz and initrd, with the same kernel config on 2.6.24-rc6/7 (make oldconfig, default answer to all questions)), it works. so it seems to me like a problem in the kernel. every wake-up setting (wake up by pci-device, rtc-alarm, modem ...) in bios is also enabled, otherwise it couldn't work in 2.6.23.12 (and windows). if you say your sky2-card works, it might be a acpi-problem not related to sky2 like i thought - when i am at home i'll try to start my pc with a timer (-- /proc/acpi/alarm) from kernel 2.6.24-rc7 to check if acpi-wakeup works and report back (if it is any help in finding the source of my problem). and regarding printk i'll try to find out what you mean (my first steps into kernel debugging :) - i think you mean adding a line in the source to print out something when the function is called) regards -- To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
