Latest ArchLinux image doesn't boot on a FAT32-filesystem, booting ARCH_2014_04 works fine (UEFI-mode).
It tries to set a charset-mode on the (FAT32)-filesystem at (usb-)boot, but fails to do so (IO charset iso8859-1 not found). Resulting in message that label cannot be found, well it is correct set.

Tested on a clean format FAT32-USB, booting to UEFI-mode.
This task depends upon

Relevant commit:

Not sure about the proper way to fix it, either through another kernel config tweak, or by simply adding the module to the ISO initramfs.
Could somebody add Thomas here?

i encounter with the same issue but i passed it remount device with cp437 iocharset
like that:
mount -t vfat -o iocharset=cp437 /dev/disks/by-label/DISKLABEL /MOUNT_POINT
(you should replace DISKLABEL and MOUNT_POINT with yours.)

after that successful mount i was able to continue to boot process with CTRL+D

p.s. nls_iso8859-1 kernel object doesn't exists in kernel modules

  • Field changed: Summary (Booting ARCH_201405 boot fail, cannot set fs (charset) options → Booting ARCH_201405 boot fail, cannot set fs (charset) options in loop mode)

  • Field changed: Category (Packages → ArchISO)
  • Field changed: Architecture (All → All)
  • Task assigned to Thomas Bächler (brain0), Gerardo Exequiel Pozzi (djgera)
@Thomas: do you want to revert this change (build nls_iso8859-1 as module instead of built-in) or I can just add_module for archiso_loop_mnt hook?

I used RUFUS (on windows) to create a boot usb mem stick using GPT and NTFS (instead of fat32) and I was able to avoid getting this error. On a baytrail mobo

This should be fixed directly in mkinitcpio, assigning to Dave.

I have the same problem with the 2014-05-01 iso, I hope next iso ( 2014-06-01 ) will fix this problem
