okay. so you are sure now that process_filesystem is called with
args '/dev/mapper/cryptoroot' and 'ext4'.
can you maybe do an ls -alh, stat, and file on $1 as the first thing in

that's really odd. so basically you are saying when the dm_crypt is
created -b on it returns true, but a bit later -b on the same thing
does not. please doublecheck that $fs_label is cryptoroot here.
do a ls -alh, stat and file here also. so we can compare.

I think it probably has something to do with open fd's such as
notice that we do some magic in process_filesystem like
cryptsetup $fs_params $opts luksFormat -q $part >$LOG 2>&1 < /dev/tty ; ret=$? #hack to give cryptsetup the approriate stdin. keep in mind we're in a loop (see process_filesystems where something else is on stdin)
infofy "Please enter your passphrase to unlock the device"
cryptsetup luksOpen $part $fs_label >$LOG 2>&1 < /dev/tty; ret=$? || ( show_warning 'cryptsetup' "Error luksOpening $part on /dev/mapper/$fs_label" ) ;;
maybe the debugging somehow affects this.
