I've got exactly the same problem with Thinkpad 600E. ibm-acpi works fine with 2.6.21 thinkpad-acpi reads the volume settings just fine with 2.6.22 but any attempt to set it results in write error. I've also tested "echo 0x30 0x01 > /proc/acpi/ibm/ecdump" and it also results in write error ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
