We use barrier=0 for Ubuntu 12.04 for the last few weeks and haven't seen an issue with it. Other than the ability to reboot and have the system come up reliably.

There has been some hint to disable barrier (adding barrier=0 in fstab), and it seems to indeed resolve the issue, cf links below. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=637234 http://www.warden.pl/2012/04/10/debian-io-disk-problem-when-rebooting-on-xenserver-guest/ I wanted to know if there are any side effect to that workaround or if it is safe?
