Comment 39 for bug 1318551

Wow.

I just spent the last 6 hours trying to solve this problem on a supermicro machine (mother board is Supermicro X9SRL-F http://www.supermicro.com/products/motherboard/Xeon/C600/X9SRL-F.cfm) before stumbling upon this ticket. Now you know that not only HP machines are concerned.

Adding the "noautogroup" by editing GRUB at boot time solved the problem for me.

The system is ubuntu 14.04.2 with a 3.13.0-53 though I experienced the issue with previous 3.13.0 kernels from the original installation of the server back in September 2014. Note that even if I am on 14.04.2, I don't use the newest LTS kernel stack (https://wiki.ubuntu.com/Kernel/LTSEnablementStack) from 14.04.2 (it means that I installed from a 14.04.1 media, the mini.iso to be exact, then upgraded).

I fixed the issue permanently with the following workaround:
- modify the following line in "/etc/default/grub" to add "noautogroup":

  GRUB_CMDLINE_LINUX_DEFAULT="splash quiet noautogroup"

- launch "sudo update-grub" to apply the configuration

I thought I was going crazy: during those 6 hours trying to fix the bug, I eventually ended up doing a fresh install (with the mini.iso though, which means that I got all last upgrades, including newer 3.13 kernel), but the problem was still there.

I seriously hope this will be fixed!
