Hi, Here is more information about the problems I mentioned in last bug report. I have tried Linux kernel-image-2.6.8-1-686 and kernel-image-2.4.27-1-686 from sarge on my IBM Thinkpad T41. However 1) my laptop can not power off or standby after I type "shutdown -h now". It hangs before completlely turning off. I think the problem probably relates to ACPI 2) cpufreqd doesn't work since it can not find the CPU interface from /sys/devices/system/cpu/cpu0/cpufreq.
I intalled kernel-image-2.6.9-1-686 from unstable. My laptop can power off but can not go to standby. The problem 2) I mentioned above still exists. I recompiled the original 2.6.9 kernel with the patches from http://www.stanford.edu/~sanjiv/thinkpad/thinkpad.html. My laptop works well and can power off and go to standby. The cpufreqd works as well. Thanks J Zou
