This is driving me nuts. I’ve had this G5 (single cpu, 1.6G) for a few months, and now it’s started rebooting randomly for no apparent reason. I finally looked in the logs today and found the culprit:\n<\/p>\n
\nJul 23 18:56:31 localhost kernel: ApplePMU::PMU FORCED SHUTDOWN, CAUSE = -122\n<\/pre>\nGoogling “PMU FORCED SHUTDOWN, CAUSE “<\/a> gave me some hits, but there were all for powerbooks and ibooks, and the fix was to reset the PMU. Searching further on Apple’s support site<\/a> yielded no direct hits on how to reset the PMU on the desktop G5, but they did have an entry for the XServe G5<\/a>. I’m going to have a look around my G5 tonight and see if I can find the PMU reset button. It’s seems overly complicated for something like this…\n<\/p>\n
Update:<\/h5>\n
The G5 was repaired at the local Apple Reseller and the PS was swapped out. Issue resolved.<\/p>\n","protected":false},"excerpt":{"rendered":"
