Are you familiar with git? If yes, then you could try and bisect the issue. You would do something ala: $ git bisect start $ git bisect good fio-1.21 $ git bisect bad fio-1.31 and then git would checkout a point in between. You would then compile and run, checking if it works or not. If the version works, then you would reply with $ git bisect good if not, then you would do $ git bisect bad This continues until git tells you which commit is the defective one. I'll give it a spin on Solaris too, I recently put Solaris 11 on a box for test purposes. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
