The S2466Ns are incredibly touchy, aren't they? When reimaging the other 19 nodes some of them had to be reset, and in a couple of cases, unplugged and plugged back in, before they all come up properly with "boel" loaded from the headnode. I never did get acpi working perfectly, just (barely) good enough. If the "button" module is loaded once, and never looked at sideways again, then after "poweroff" the front panel switch works to restart the system. Turn acpi on, or even just do: rmmod button; modprobe button and that front panel switch won't work after "poweroff". Never could get acpid working at the same time, so no way to trigger a shutdown from the power button. That's less of a problem though, since historically if "rsh nodename; poweroff" doesn't get through, it's about 50% odds that that node will also ignore its reset and power buttons. Anyway, the two main reasons for upgrading these nodes were: 1. Get athcool working. This knocks about 50W/CPU off the idle power consumption and drops the idle CPU temps from 39C to 29C. (A previous fling with athcool and the previous kernel did not work.) 2. Hopefully eliminate a bug in i2c that was causing sensors to stop working every once in a while, resulting in node shutdowns because the Over Temp scripts would suddenly be unable to obtain valid temperature or fan speed measurements.
