Didn't try these kernels yet but, for posterity : All reboot tests are made with console mode (CTRL + ALT + F1) and CTRL + ALT + SUPPR
Sometimes, reboot hungs on apache. I had a problem with apache2, which doesn't want to pass because of there wasn't "ServerName localhost" options in /etc/apache2/apache2.conf. Still not clean reboot : Before, every computer, at every time hangs. I added "reboot=pci" kernel option in /etc/default/grub, and now, if a computer was rebooted few minutes before a new reboot try, the problem comes 1 times on 10. It hangs after all K** in rc6.d. I noticed that, the difference between computers that reboot properly and those which do not is a log line : "Rpcbind terminated on signal" : when this line apear, one second later, the computer reboots properly. I googled it and saw that RPCbind has a report with NFS and that, that is "S20sendsigs" which send this signal. Here my rc6.d dir : lrwxrwxrwx 1 root root 21 avril 23 11:09 K01sifupdate64 -> ../init.d/sifupdate64 lrwxrwxrwx 1 root root 27 avril 23 11:11 K02sifrebootdefrozer -> ../init.d/sifrebootdefrozer lrwxrwxrwx 1 root root 17 oct. 17 2013 K08tomcat7 -> ../init.d/tomcat7 lrwxrwxrwx 1 root root 17 oct. 17 2013 K09apache2 -> ../init.d/apache2 lrwxrwxrwx 1 root root 29 oct. 16 2013 K10unattended-upgrades -> ../init.d/unattended-upgrades lrwxrwxrwx 1 root root 21 oct. 17 2013 K20libnss-ldap -> ../init.d/libnss-ldap lrwxrwxrwx 1 root root 14 oct. 17 2013 K20nscd -> ../init.d/nscd lrwxrwxrwx 1 root root 15 oct. 17 2013 K20nslcd -> ../init.d/nslcd lrwxrwxrwx 1 root root 27 oct. 16 2013 K20speech-dispatcher -> ../init.d/speech-dispatcher lrwxrwxrwx 1 root root 20 nov. 4 10:18 K20virtualbox -> ../init.d/virtualbox lrwxrwxrwx 1 root root 17 févr. 11 16:22 K20winbind -> ../init.d/winbind lrwxrwxrwx 1 root root 20 janv. 20 14:27 K20x2goserver -> ../init.d/x2goserver lrwxrwxrwx 1 root root 18 oct. 17 2013 K79quotarpc -> ../init.d/quotarpc lrwxrwxrwx 1 root root 27 oct. 17 2013 K80nfs-kernel-server -> ../init.d/nfs-kernel-server lrwxrwxrwx 1 root root 15 oct. 17 2013 K85quota -> ../init.d/quota -rw-r--r-- 1 root root 351 juil. 26 2012 README lrwxrwxrwx 1 root root 18 oct. 16 2013 S20sendsigs -> ../init.d/sendsigs lrwxrwxrwx 1 root root 17 oct. 16 2013 S30urandom -> ../init.d/urandom lrwxrwxrwx 1 root root 22 oct. 16 2013 S31umountnfs.sh -> ../init.d/umountnfs.sh lrwxrwxrwx 1 root root 20 oct. 16 2013 S35networking -> ../init.d/networking lrwxrwxrwx 1 root root 18 oct. 16 2013 S40umountfs -> ../init.d/umountfs lrwxrwxrwx 1 root root 20 oct. 16 2013 S60umountroot -> ../init.d/umountroot lrwxrwxrwx 1 root root 16 oct. 16 2013 S90reboot -> ../init.d/reboot I don't know where autofs is shutting down. So i thank that umountnfs.sh was executed before autofs closed. So, I created a script sifrebootdefrozen which contains : #!/bin/bash service autofs stop sleep 2 And place it in K02. When it is executed, i saw on screen "autofs already closed" or something like that. So that's not the problem. If I wait for 30 minutes or more, a new problem appears, reboot hangs on black screen, only "acpid exiting" diplayed. I tried every "acpi=" kernel options in /etc/default/grub. Still same problem, so i removed acpid (with its dependence acpi-support) apt-get remove acpid (key words for googling) I don't have acpid log line diplayed. Acpi is clearly not the problem too. So i excluded every others parameters, i can now test kernels in a cleaner way.
