Since today, the kernel refuses to start, the official one linux-4.13.11-1 and also the linux-ck-core2 4.13.11-1. It says: Unable to handle kernel null pointer dereference 0000000000000014 (here are the pics: https://ibb.co/nPK0dG and https://ibb.co/bNc0Cb ). I can enter into the recovery mode and everything is fine, I can access my disk and all. At first I thought it was a problem with the fstab file, and it was messed up indeed (it was a directory with a freepats.cfg file inside (?)). I fixed it with genfstab, but the problem remains. I've also tried reinstalling the kernel, but the problem remains. Please, what can I do to fix this?
EDIT: installed linux-lts, works just fine. I guess it's a bug in linux 4.13.11.

Welcome to the arch linux forums chachi1. What Kernel_parameters is the system using in particular is the elevator parameter being used?

Thanks! I have these lines in /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="text acpi_sleep=nonvs elevator=bfq"
GRUB_CMDLINE_LINUX=""

elevator=bfq
That will cause an oops when the device is not block-mq enabled this issue has been present since 4.12. https://bugzilla.kernel.org/show_bug.cgi?id=196695
See https://bbs.archlinux.org/viewtopic.php?id=111715&p=127 and the previous 2 pages for discussion relating to this for linux-ck.
