The commit that made it quite robust was 6687a97d4041f996f725902d2990e5de6ef5cbe5, as of March 2006, and first showed up in 2.6.17. (OTOH, since the merge of lockdep the main source of soft lockups in the field has been quite severely reduced. Nevertheless it's still good to have it around, occasionally there happen other types of soft lockups too, in open-coded loops, etc.) Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
