Sigh, the problem has come back again. I use suspend on lid close, and it seems to happen on wake from suspend. Before suspend everything is fine, after wake it often (about 1/4 of the time) has this speed problem. Current kernel: 2.6.32-24-generic #38-Ubuntu SMP Mon Jul 5 09:22:14 UTC 2010 i686 GNU/Linux
