Is this problem new in 3.1, or is it also present in 2.6.39 or 3.0? Also, do any other cmdline parmaters besides acpi=off work-around it? pci=noacpi maxcpus=1 etc. thanks, Len Brown, Intel Open Source Technology Center -- 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
