------- Additional Comments From [EMAIL PROTECTED] 2006-08-02 15:22 ------- OK - here are a few more tests. Always, ec_intr=0, and cold reboots. Experiment A) Linux2.6.17.1 single init 3 rmmod battery cd /proc/acpi modprobe speedstep-smi echo on > ibm/light #works dmesg > dmesgA.txt Experiment B) Linux2.6.17.1 single init 3 rmmod battery cd /proc/acpi modprobe speedstep-smi cat ibm/thermal #works echo on > ibm/light #fails dmesg > dmesgB.txt Experiment C) Linux2.6.17.1 single init 3 rmmod battery cd /proc/acpi #modprobe speedstep-smi #NOTE: I did not load speedstep-smi. cat ibm/thermal #works echo on > ibm/light #works dmesg > dmesgC.txt Experiment D) Linux2.6.17.1 single init 3 rmmod battery cd /proc/acpi modprobe speedstep-smi echo on > ibm/light #works echo off > ibm/light #works cat ibm/thermal #works echo on > ibm/light #fails dmesg > dmesgD.txt Experiment E) Linux2.6.17.1 single init 3 rmmod battery cd /proc/acpi modprobe speedstep-smi Press Fn-F12. This triggers acpid, which responds to /etc/acpi/events/fn-f12 by running /etc/acpi/actions/fn-f12.sh, which flashes the thinklight 3 times. #works cat ibm/thermal #works echo on > ibm/light #works dmesg > dmesgE.txt Thus, it really does appear that speedstep-smi MUST be followed by a physical button press before anything in /proc/acpi is read. Otherwise, any subsequent writes to /proc/acpi/ will fail. Attachment to follow (is there any way to add an attachment to a comment?). ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- Take Surveys.
