It's not clear to me if the test failed for you or just got stuck. The
output below is all "[ OK ]".

I ran the test with my patch and got:

Tests passed: 875
Tests failed:   5

I don't believe the failures are related to my patch given the test
doesn't use bonding.

See more below.

If the test got stuck, then it might be related to the deadlock in
iwlwifi. Try running the test without iwlwifi and see if it helps. If
not, I suggest starting a different thread about this issue.

Will submit the bonding patch over the weekend.

Thanks for testing
