I belive that the syntax is ./runltp -f ipc
Also there are additional tests for POSIX IPC in open_posix_testsuite
that are not executed by the runltp script.

There are certain testcases that needs a separate filesystem partition
to play with, if you don't pass physical disk partition to the runtest
script a loopback device is created, formatted and mounted.

This simply looks like the 10MB image is not enough for the ext4 journal
for some reason.
Try following patch that increases the size to 100MB.
diff --git a/runltp b/runltp
