Every time I boot with a fresh JFFS2 image or if I remove som big files and reboot(does not matter if I wait before I reboot), kupdate runs like hell, consuming almost all cpu for a while before it calms down. If I monitor the output from 'df', I see that the Use field slowly rises to 100% and then its drops back to my real usage of the JFFS2 partition.
