[Solved] Kernel 3.14.6-1 modules load on boot problem

Hi,

I recently ran an update and the kernel got updated to 3.14.6-1, since then the system won't boot. Systemd-modules-load.servie fails because it can't load some modules, but I'm thinking it doesn't boot because of not being able to mount /proc/xen (which requires xenfs module to be loaded).

Output of "grep xen /mnt/arch/usr/lib/modules/3.14.6-1-ARCH/modules.alias":

alias xen:pci xen_pcifront
alias xen:vfb xen_fbfront
alias fs-xenfs xenfs
alias xen-backend:pci xen_pciback
alias xen:vtpm xen_tpmfront
alias xenblk xen_blkfront

alias xennet xen_netfront
alias xen:vif xen_netfront
alias xen-backend:vif xen_netback
alias xen:vkbd xen_kbdfront

"modinfo xenfs" says module alias can't be found.
Although I can see that all of the modules required are available, output of "find /mnt/arch/usr/lib/modules/3.14.6-1-ARCH/ -name "*xen*"" is:

/mnt/arch/usr/lib/modules/3.14.6-1-ARCH/kernel/drivers/xen/xen-gntdev.ko.gz

Other than xen modules a few others fail to load as well. Those include broadcom, tun, tg3, nfs, ... . Like xen modules all the ko.gz files are available.

I don't have much info about kernel modules and how systemd deals with them, I'd appreciate if someone could help.

UPDATE:
I realized that uname -r says my kernel version is 3.14.5-1, this is confusing

Thanks for the answer, but the actual problem was a little different.
The boot partition had been unmounted before update, so the kernel binary file was written to the /boot of the / partition. And becuase modprobe uses kernel version to find the modules it couldnt locate /usr/lib/modules/3.14.6-1-ARCH and you see where this is going...
