If causes an assert failure on a DEBUG kernel, a shutdown on a non-debug kernel. Either way, I'd prefer to leave it enabled as a good reminder that we need to fix the damn bug (*) sooner rather than later... (*) This patch prevents the assert failure, but, like Lachlan, I'm not sure it is the right fix. http://oss.sgi.com/archives/xfs/2010-09/msg00337.html I'm working on it at the moment, along with all the other allocation things...
