I tried to run away from input06 test. This error remains.

How do I avoid the error ? Thanks!

Regarding getaddrinfo_01.

Just assign a resolvable hostname to you host.

Or add the current hostname to /etc/hosts:

echo "127.0.0.1 debian" >> /etc/hosts echo "::1 debian" >> /etc/hosts

The input06 messages are red herring here, all it says is that it couldn't test input subsystem because there is no uinput compiled in kernel or as a module.

Looking into the LTP source the test that creates the sandbox directory is testscripts/test_fs_bind.sh. Most likely something went wrong in the test and something stayed being mounted under the sandbox directory after the test has exited, or the test became stuck before it had chance to clean up and is still running on background.

I suggested that the reason for inconsistent running tests on different architectures. The script test_fs_bind.sh out by mistake after 5 tests. I get tests list of testscripts/test_fs_bind.sh. Arrange running tests starting at 1. The script test_fs_bind.sh not out by mistake. But get this error again.

Run command: 

find "testcases/bin/fs_bind/move/" -type f -name 'test*'

result on Mips architecture:

I add umount "${sandbox}" in test_fs_bind.sh before rm -rf "${sandbox}" and fix problem with sandbox but i don't know correct solution. I have error rm: cannot remove ‘/tmp/ltp-EyOqzruY93/hugz82UVp’: Device or resource busy still.
