According to this bug report (https://bugzilla.novell.com/show_bug.cgi?id=229210) the problem may be due to bad interaction between libata and the shutdown command. Tejun Heo, whom I thank for his support, has already proposed a patch to fix this. From the description there, it looks like it may also fix the reboot problem this thread is about. Regards
