I've jsut upgraded from 5.3-STABLE to -CURRENT, and have a few things I've noticed. One, my machine runs much hotter - it used to stay around 40 - 41C, but not stays around 49C. Also, it actually seems like it's running slower - and maybe it is. It looks like the cpu frequency is changing all the time, hopping around from one freq to another, for no real reason that I can tell. I'm running on a dell D600 (1.6GHZ Pentium M), with -CURRENT as of last night. I can provide any additional information needed..
