Can you test the patch below? Cheers, Dave. -- Dave Chinner david@fromorbit.com xfs: fix dquot shaker deadlock From: Dave Chinner <dchinner@redhat.com> Commit 368e136 ("xfs: remove duplicate code from dquot reclaim") fails to unlock the dquot freelist when the number of loop restarts is exceeded in xfs_qm_dqreclaim_one(). This causes hangs in memory reclaim. Remove the bogus loop exit check that causes the problem.

However, there's now a new crash -- not sure how related this is but at some of the stack traces involve XFS. Any ideas? Unlike the last one, I could apparently recover the kernel with sysrq-i.
