If so, we(Nanhai and myself) will take a look at VMEMMAP changes and see if the bug that the commit 2e1c49db4c640b35df13889b86b9d62215ade4b6 tries to fix is still open in the latest git. But I can't explain how 2e1c49db4c640b35df13889b86b9d62215ade4b6 can be the root cause of Dave's issue in 2.6.23. thanks, suresh - 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/
