Public bug reported: I've moved my main machine from an ASUS 1001P netbook to a Lenovo Thinkpad X200 Tablet and continue to experience high CPU load from Xorg. In case of the 1001P , I had reported this as bug 1087535. I am opening a new ticket since the underlying hardware changed. When moving to the new machine I simply swapped the HD out of the old and into the new machine. I am still trying to figure out what is causing these high loads of 100% for one core. It seems to me that network activity is a contributing factor, particularly if the network is unstable. I believe many open tabs in FF lead to this situation.
