Can anyone set my mind at rest? (Or suggest a fix?)

Those kernels will be in common use for some time to come, and this fix is more or less essential. ??? - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
