My main concern was the adaptec aic7 and aic9 series, and i am aware that a one-time loading device should have good chances to succeed, i dont call it critical for my particular application case (some few Gigs main memory). But as the very same problem exists all over the place, even in USB devices - which can be plugged and unplugged any now and then. Producing a memory leak of a few 10 to 100 kB on every plug and remove is nothing really acceptable for a system that is expected to have longer uptimes. So if there are some solutions out there for getting the return value interpreted and in the error case the device registering canceled, then i asked if the respective coders and maintainers could pop up for getting thoses messages removed from the compiler`s output. Can you please? I just dont want to duplicate any works here, or much worser code something that no one with a better understanding would ever integrate into the kernel. -Alex. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
