Failed to mount /boot

At startup I see the message

[FAILED] Failed to mount /boot

and then it enters emergency mode. I am able to login and check that the efi partition is not mounted.

Before "Failed to mount /boot" I can see

Oops: invalid opcode: 0000 [#1] PREEMPT SMP MOPTI

followed by some debug information.

Everything was working normally until yesterday. This is possibly related to my other active forum post involving the usb installer.

Re: Failed to mount /boot

Comment the /boot entry in your fstab, will likely allow you to boot.
Compare "uname -a" and "pacman -Qs kernel"

The cause is likely that you forgot to mount that partition when updating the kernel from the chroot?
To check what kidn of location you're booting from:

cat /proc/cmdline

re-installing the kernel w/ the boot partion properly mounted would then fix this.
