It should already have all ext4/jbd2 patches from next-20090310, but anyway it happened with 2.6.29-rc8 also. I ran dbench in cycle on two indentical hosts for more than 24 hours with no hang tasks. I will try 2.6.29. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
