Bug#840400: Issue seems in nls_ascii module not available

[Thomas Wuensche <wuensche@ems-wuensche.com>]

I also had that problem and could work around by loading nls_ascii.ko
module manually. It turned out that the vfat mount to access the EFI
partition failed due to lack of ASCII IO charset.

So I guess the reason for the bug is the lack of a loaded nls_ascii
module at the time when the partition should be prepared and mounted
during the install.
