Hi, this was discussed before, but I thought the problem was solved. Apparently not... After upgrading to 2.6.25, jiffies on my 2xdual-core IBM x3650 boxes seem to jump back and forth as can be seen on the dmesg output. Did not happen in 2.6.24. As I did not follow the rc-cycles for 2.6.25, I cannot really say when it started. Config attached.
