I assume you don't actually have any of the > hardware, you're just randomly inserting the modules? correct. As i mentioned it in the first sentence this is an allyesconfig bzImage bootup. I.e. this is the bootup log of a "make allyesconfig" kernel - roughly analogous to (trying to) insert every module in existence. In the boot log you'll find 4871 initcalls, done by over 3000 drivers that each is attempted to be loaded by the kernel (!). I do those bootups to "run as much as possible" kernel code and to make sure that the maximum combination of debug and other features still produces a working kernel. I had to work half a year to gradually get the kernel to that stage (started with it more than a year ago, as part of the -rt kernel) but these days i'm booting a 32-bit and a 64-bit allyesconfig bzImage kernel almost daily :) These bootups already caught a healthy amount of bugs in the kernel, both important and unimportant ones. Recently the size of the allyesconfig bzImage kernel surpassed 42MB, so it's massive. Btw., i also boot "allnoconfig" kernels. [with just the minimal set of features turned on to make the kernel minimally boot up and report back via networking.] Ingo -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
