Ummm, okay - its not the stock kernel, but I had the same heating issue with stock kernel too. To confirm, will try with the stock and then report my findings. > Setting hw.setperf to 0 isn't a "resolution" but a burying the > problem where you don't see it, for now...or then.

After extensive searching, I came across a lenovo forum thread which indicates that X60 series has the wireless card underneath the right palm-rest, which makes them hot when wireless is being used. Apparently this is a design issue with the X60, and the thread is here: http://forums.lenovo.com/lnv/board/message?board.id=X_Series_Thinkpads&message.id=22&query.id=204119 Though, as you say, the real problem for OBSD is not addressed. Earlier, the laptop used to heat up considerably even when using wired connection (and wireless being disabled by h/w switch). Once hw.setperf was set to 0, the heating became bearable (I was suggested this workaround on misc@ itself). Since it did the trick, I did not bother, until now when the heating re-surfaced. On Windows XP, the laptop does NOT heat up so much, which means there is something else with OBSD, than merely being an X60 problem. I will investigate further with the stock kernel, and then will post my findings. Thanks. -Amarendra
