The bug is now fixed in the development tree, but until you upgrade
to a kernel with the fix enabling CONFIG_LBD will keep you from hitting
the bug.

As you unfortunately noticed the !CONFIG_LBD case doesn't really get
much test coverage, so I would personally recommend turning it on even
if you don't need it.
