So.. I went from 2.6.20-mm1 back to 2.6.21-rc1 the other day and have since been happily suspending via lid closure maybe ten times a day. Any more suggestions about how to debug this? How does the suspend happen, anyway? Is it acpid's job to read the LID0/state file and to then poke /sys/power/state? Or is that linkage in-kernel? - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
