The solution for this was to set allow_unsupported_modules to 1 in /etc/modprobe.d before running make. Original text below

----------------------------------
Hi all,

I recompiled the kernel on my (SLES 11.3) box. I'm happy with the process for doing that, and it all seemed to work successfully, but I am unable to boot into the recompiled kernel.

I recompiled 2.6.32-12.0.7-default, no patches, just changed some options to do with timing and set the localversion string. Trying to boot into it gives lots of these errors:

FATAL: module '/lib/modules/2.6.32.12-0.7-modified/kernel/drivers/xxx/xxxx.ko' is unsupported.

I can still boot into the default kernel with no issues. Can anyone shed some light on this for me?

Thanks in advance for any help

Can it be a version mismatch? What module are you trying to install? Check if it is the version intended for the kernel version you recompiled: they have to match.

Hi,

This happens while trying to boot, I'm not trying to install anything. It's a whole bunch of them under /kernel/drivers that are erroring, e.g. libata, ide-core.

[Edit: I checked and these have definitely been recompiled when the kernel was recompiled, and the path it is looking for them in is correct, so I'm not sure why they are giving errors. Trying to apply the fix suggested below the error (setting --allow-unsupported) simply changes the error to FATAL: error inserting <x>: Invalid module format']

it is possible that you did not build the kernel correctly

also is this SUSE Enterprise Linux ( Desktop or Server ) 11 service pack 3 -- still supported

or
Is it openSUSE 11.3

if opensuse that 11.3 is not supported any more
there will NEVER be updates to it . The only support version in 11 is 11.4


So with out knowing WHAT kernel you built ( the version # ) and WHAT patches you included ?

And did you REBUILD the boot image for this "custom " kernel ?

Without the needed information ,there is not much we can do to help .

Sorry, this is SLES 11.3, I mistyped. I've updated the OP to reflect more accurately what steps I have done etc and the errors I am getting.

Just to report back on this in case anyone else has similar issues -

The fix was to ensure that allow_unsupported_modules was set to 1 in /etc/modprobe.d before running make modules. Only re-running 'make modules_install' with it set did not work.
