Hi,
I just want to add to this discussion that this problem also occurs on my T61 with only Linux installed on it.
"reboot=pci" also removed the reboot delay here.
If you need some further information or want me to try some patches / old kernels I'd be glad to help.
Regards,
Jens

Hi!
Just a quick me too: I'm on Lenovo R61. reboot=pci gives instantaneous
reboot, reboot=acpi and default-reboot delays for 9 seconds...
Cheers,
