LFS 6.4
Kernel 2.6.27.4
System 16GB USB 2.0 stick

When my system starts up I get the following messages:

Driver 'sd' needs updating - please use bus_type methods
Driver 'sr' needs updating - please use bus_type methods

Where would I get the drivers to update and what are bus_type methods? As my
system does boot up ok and I can mount my SATA drive and CD and DVDs
anyway.

I assume it's the kernel source that needs updating as I never got these messages when using kernels 2.6.22.5 and 2.6.22.9

Anyone else getting these messages?

Thanks.

did you enable support for those scsi devises when building your kernel. did you make modules_install ? SR and SD are scsi devises small computerized system integrated
if every thing works then it is ok. why the drivers for those devices are in the kernel already. your old scripts. init scripts need updating to load new parts of the kernel.
so when you start up the scripts do not see the modules where they were in the old scripts the out put is upgrade. were as commercial distro's the read out is module already installed in kernel.
update your init scripts for your kernel. or configure your kernel sata and scsi support.

Thanks for your answer, however:

No I didn't as I built a monolithic kernel with everything I needed in it

There aren't any old init scripts as this is a completely new build. Anyway these messages appear before init runs.

Yes I have done this otherwise my system would not have started at all.
Any other suggestions would be much appreciated.

Thanks

It looks like these messages are nothing to worry about and are purely for the kernel developers.

See http://bbs.archlinux.org/viewtopic.php?id=67934 and
http://marc.info/?l=linux-scsi&m=121000463825804&w=2
for more info.

And we all do that to linux is a monolithic kernel and the kernel is loaded with the init. build with support for the modules.
well if you don't make modules in stall on a new kernel version then when you add new hardware you could be in a bind. because not all hardware will load from just loading the kerenel.
I configure my kernel to be small but support many drivers. if the kernel is to big then you will find some wrong stuff being loaded.
But if you are building for a certain system then your right. Good luck.

Dear gazzalz,

Thank you for clearing this up. My system, also a clean install (Gentoo 2.6.28-r5) has the same problem with the following on startup:

It is encouraging to have two references showing that these are developer chatter and nothing that should cause problems for users.

Thanks again!

Actually the kernel calls init, not the reverse.

BIOS -->MBR -->Linux Kernel ---> INIT ---> runlevel and scripts
