kernel vermagic

env kernel 2.6.12

i recompile the kernel to change from M686

now i get vermagic error when i load modules...
the EXTRAVERSION parameter in the Makefile
is correct infact modules are installed in the same old libary...
in the past this kernel was recopiled succesfully...

a sample of the error:

evdev: version magic "2.6.12-12mdk PENTIUMIII gcc-4.0" should be "2.6.12-12mdk 686 gcc-4.0"

as you know the name of the kernel is unchanged
2.6.12-12mdk but the machine name is PENTIUMIII instead of 686 ...
but this is what i have changed to my kernel ,because the machine is a PENTIUMIII intel celeron coppermine....

any help will be appreciated

Have you tried recompiling the affected modules?

Yes, definitely recompile the modules if you haven't. The kernel name may be the same, but the innards of it are not, and the OS knows this.

to be more precise.
here what happened
1) make bzImage ...runs fine.
2) i added the vmlinuz anf the to boot
directory and update lilo
3)linux boots up fine
4)make modules runs fine
5)make modules_install runs fine..the module are installed in the right library...
6)at this point when i boot linux i get the error described in the first update.

what make me "crazy" that processor type is a kernel parameter...infact
kernel code compiled as modules reflect this...but the system still has 686
as machine type..

so kernel modules where already recompiled.
"uname -m" return 686 as machine type...

any help will be appreciated ...

thanks in advance

the README file on the kernel source directory
instruct to execute
make install
make modules_install

this fix the problem.

i followed the old procedure,but this seems to lacks about machine name.
