Hi all just to state that building a 2.6.24-0.57.rc3.git4.local.fc8 kernel from the rawhide source rpm has cured the problem. The battery has been recognised and /proc/acpi/ has been populated with all the required information to allow thermal monitoring. Hope this is of use to anyone else with the same problem. mike -- This is an email sent via The Fedora Community Portal https://fcp.surfsite.org https://fcp.surfsite.org/modules/newbb/viewtopic.php?post_id=224171&topic_id=47985&forum=10#forumpost224171 If you think, this is spam, please report this to webmaster@xxxxxxxxxxxxxxxx and/or blame mikie.simpson@xxxxxxxxxx
