Now you might be able imagine what CPU Context Corrupt can mean. Since the CPU Context is usually stored in RAM it is very likely, that your RAM has prolems. For fast task switches the CPU context can also be stored in the CPU tself, so there is also the chance, that your cpu is bad. Hope that helps, I'd run a memtest again, if you don't find anything it is probably the CPU. > In Idle Task - Not Syncing > > I've found parts of the error on google... references to various things. > The one almost exact match I got was here: > http://www.ussg.iu.edu/hypermail/linux/kernel/0201.3/0382.html > > Sometimes the quoted problem is memory, or clock speed.
