I see this on my HP Microserver already for some time, but it is present also in 3.16.0. Not sure what is causing this.

Comment 1 j.fikar 2015-01-29 13:52:34 UTC

the problem is in initramfs created by dracut without systemd but with udev, more information here:

https://bugzilla.kernel.org/show_bug.cgi?id=65661

https://bugs.gentoo.org/show_bug.cgi?id=462928

as I don't want systemd, it is enough to build initramfs by dracut in chrooted enviroment, which has systemd installed

anyway I guess kernel should not oops on userland program even if it is in initramfs, should it?
