There's two possibilities here: 1) Lenovo's firmware is broken and the 9-second delay is always going to be there. In that case we should try to use the ACPI reboot vector first. 2) We're doing something wrong in our shutdown sequence which then triggers this problem as a result. Either way, I think this patch is wrong. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
