I agree, but I didn't want to make any sort of drastic changes to scsi.c
in Aurora (I'm still getting my feet wet here!).
As to the claim that this is broken solely due to Aurora being broken, I
can dispell that simply by pointing to the fact that Red Hat Linux 7.3
exhibits this behavior as shipped, on machines where the scsi drivers
are modular. dmesg log from 2.4.18-3smp is attached to this email.
In fact, sunesp is modular in Aurora, which is how this issue came to
light. When I made the change from compiled in to modular (and started
using an initrd), several testers reported this as a bug.
Feel free to correct me (and Doug) if I'm wrong, because I cede that you
know a HELL of a lot more about this than I do. My Aurora kernels use
this, the scsi subsystem works (the modules all load as they should),
and I don't have a kmod error message in dmesg.
For reference, Aurora builds kernels with the following relevant
options:
CONFIG_MODULES=y
CONFIG_MODVERSIONS=y
CONFIG_KMOD=y
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_SCSI_SUNESP=m
The Red Hat Linux 7.3 i686 config builds kernels with the following
relevant options:
CONFIG_MODULES=y
CONFIG_MODVERSIONS=y
CONFIG_KMOD=y
CONFIG_SCSI=m
CONFIG_BLK_DEV_SD=m
CONFIG_SCSI_AIC7XXX=m
As a result of further testing and thought, I definitely agree with
Doug. The patch that I originally submitted will only get rid of the
kmod error noise when BLK_DEV_SD is compiled into the kernel. Perhaps
this block of code should die? I'll leave that to the experts to decide.
