I have a Dell Inspiron 8600 laptop, that has recently stopped being able to shut down. It seems to have occurred since a yum upgrade I performed on March 31, which included kernel 2.6.16-1.2069_FC4, glibc 2.3.6-2 and selinux-policy-targeted 1.27.1-2.28. The symptom is that when running the shutdown command (either via gnome or the command line), no processes are terminated, nothing is logged in /var/log/syslog or dmesg. An strace shows shutdown waiting on a futex. I have tried (one at a time) the previous kernel (2.6.15-1.1831_FC4), tried disabling SELinux, and tried manually killing individual processes until I'm just left with the shell I am running, mingetty, and kernel procs. Still can't shutdown. My grub kernel line is: kernel /boot/vmlinuz-2.6.16-1.2069_FC4 ro root=LABEL=/ rhgb quiet Any advice (or similar experiences) appreciated. Cheers, Ben
