If the clock is off then plenty of things can go wrong. - system load. Perhaps the system is too busy for LMS to run well. - network status and interface parameters. Perhaps the machine renews its DHCP lease or renegociates link parameters with the switch. - possibly hard drives/data links parameters.
I've seen all this go wrong (and much more) when suspending linux machines. Trying all suspend quirks can't really harm. Also, I don't know how the PM system you're using works, but what I do personally is to stop services, unload kernel modulesÂ… as needed before sleep, and restart these upon wake-up. A friendly machine (and kernel) won't need anything special; temperamental ones can do really funny things until you've found the exact issue and solve it at sleep time. My debugging method is about this : - unplug anything unnecessary from the machine, including networking. Keep only keyboard/console. - check the bios is reasonably recent (beware of a 1.0 version), set to reasonable parameters, that the cmos battery is not depleted (can cause time/date issues.) - try suspend with my system running a minimal set of services (something like single mode, with ACPI active). It should work (perform normally). - if it does not work, look for people with similar problems and the same hardware. Try a newer/older version of linux. Kernel versions do matter, unfortunately. - if it does work, check it works repeatedly, and not a single time. Also, check the machine does reboot and shutdown correctly after sleep/wake cyclesÂ… - then gradually add the hardware/drivers apps you want to run and see when it starts to break. As already said, on some setups I've had to proceed to quite a few seemingly futile stop/starts. However, I have yet to see the need to restart LMS. ------------------------------------------------------------------------ epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=48521
