any word on this?
Comment 4 Sam Ravnborg 2006-08-03 14:11:56 UTC
Thanks for the report.

There is an ongoing effort to fix the section mismatch warnings in the kernel.
With recent GCC the .smp_locks warning started to show up - it was a limitation
in the section mismatch check code.

That particular warning are fixed in 2.6.17 - and it is assumed it was this
warning that triggerd this report. So bug is closed.

Comment 5 Tobias Powalowski 2006-08-03 23:53:37 UTC
sorry still not fixed in 2.6.18rc3git1
Comment 6 Sam Ravnborg 2006-08-04 00:04:28 UTC
The section mismatch warning are still valid for many modules - not all modules
are fixed.
Please include list of warnings - if they are mostly real warnings that require
driver fixing then this bug is not suitable.
If there is a feneral type of warning that should not be there and needs
spression in modpost then this bug is valid.

warnings during make modules 2.6.18rc3-git5

new file added 2.6.18rc3-git5
Comment 8 Sam Ravnborg 2006-08-04 01:33:14 UTC
The list of warnings are now down the real bugs in a few number of drivers.
When classified as real does not necessarily imply a real bug but mainly that
there are references between two incompatible sections.

Sp I suggest to close this bug since the general issue is deal with and now we
only have to address the few remaining drivers (there are more than reported here).
