At the moment, there are two ways to control the unaligned message printing: - use the dmesg command to lower the printing threshold below KERN_WARNING ("dmesg -n4", IIRC) - use prctl --unalign=silent to turn off unaligned printing for a particular task and its children If these mechanisms are not sufficient, there is nothing to stop anyone from cooking up a patch. For my puposes, what's there works nicely so I myself have no plans to make changes in this area. --david - 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/
