[SOLVED] Unable to load fuse, mount vfat /boot after kernel upgrade

Yesterday I ran a -Syu and apparently a kernel update was part of that. Today, I was originally unable to boot from Gummiboot on my IdeaPad Z580 UEFI system, but after chrooting from a live system and replacing the kernel and initramfs-linux.img on my UEFI boot partition with those present in my root partition's /boot directory, I am able to boot into emergency mode.

When I boot into emergency mode, the system tries to mount my UEFI boot partition and my Windows partition. Both operations fail, presumably because the vfat/ntfs drivers don't get loaded. I believe this is because the fuse module is not loading. Running "modprobe fuse" or "modprobe -v fuse" or "modprobe -R fuse" yields no output. I see in various logs phrases like "could not find alias fuse", but I have no idea what this means.

Any ideas?

EDIT: I have an x86_64 system.

Re: [SOLVED] Unable to load fuse, mount vfat /boot after kernel upgrade

I'm not familiar with fuse or emergency mode, but some things come to mind:

1) Lack of output is odd, but the version of modprobe contained in emergency mode may not be identical to the standard one. So maybe the behaviour is normal. Note with the standard modprobe you can also multiple -v flags to get more info (modprobe -vv;modprobe -vvv; etc).
2) Is the fuse module even available? Try finding it in the filesystem. If it is available, it may be necessary to modprobe it with full path and extensions.
3) "could not find alias fuse" - modprobe allows you to give alternate names for a module with aliases via .conf files in /{lib,etc}/modprobe.d/ . But this probably has nothing to do with your problem. You can find more in the man for modprobe.d when you get running.

Re: [SOLVED] Unable to load fuse, mount vfat /boot after kernel upgrade

Solved the problem by mounting from live USB, chrooting, cd'ing to /var/cache/pacman/pkg and downgrading the kernel to 3.9.2-1 from 3.9.3-1.

I will have to see what can be done when I upgrade later to avoid this problem with the kernel modules not working after upgrading.
