Hi, With the new kernel 2.6.29 version loading thinkpad_ec needs force_io=1. The kernel version 2.6.28 worked without this parameter. Can I use force_io=1 without to worry about? thinkpad_ec: cannot claim IO ports 0x1600-0x161f... consider using force_io=1. tp-smapi 0.40 (from Debian/sid package) ThinkPad T61 (BIOS 7LETC5WW (2.25 ), EC 7KHT24WW-1.08) Regards, Kai
