FYI: Subject : Thinkpad R50p: boot fail with (lapic && on_battery) References : http://lkml.org/lkml/2006/10/31/333 Submitter : Ernst Herzberg <earny at net4u.de> Status : submitter was asked to bisect It seems to be completely unrelated (except that it's also a ThinkPad), but it might be worth a try whether a (non-SMP) kernel without APIC support fixes the issues after resume. Hugh, your laptop seems to be a non-SMP laptop. Do you have APIC enabled, and if yes does disabling help? cu Adrian VERSION = 2 PATCHLEVEL = 6 SUBLEVEL = 19 EXTRAVERSION = -rc4 NAME=ThinkPad Killer
