generic/308 for xfs in xfstests test suite will hang on i386 system

This test case (generic/308) will hang on i386 system and gets killed when our timeout setting kicks-in.

Discussion could be found here:
https://lkml.org/lkml/2015/9/26/466

The patch in the mail thread was not applied.

I think we need to update our repo first to see if this is something related to the xfstest test suite itself.
