That is kind of annoying.
I am going to follow the instructions from http://neuro.me.uk/2009/09/20/revert-to-standard-ubuntu-kernel-on-ovh-or-kimsufi-servers/ later this weekend, and get back to a standard kernel. Or next week.
So if the server goes does down, that’s why!
Update: Not happening this weekend! Too much work to do.
Update 2: Did it. It works. No problems there.
