Yes, the e820 table differs, but power off still works. Hmm, there seems to be two bugs here. 1. invalid e820 tables, which seems like a BIOS bug, please try to upgrade your BIOS. 2. poweroff doesn't work. Hmm, please try boot option "acpi=off" in both 2.6.25 and 2.6.26. I guess power off works on 2.6.25 while it fails on 2.6.26, right? thanks, rui -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
