Yes I thought so. There are 2 other compile errors, but I didn't include
those as they appear trivial.
I fixed the above:

replaced machine_restart(NULL) with  emergency_restart() (Note the NULL)

Not sure about this.

1.2.4 compiles and runs fine. I actually move the modules out of "extra"
for both 1.2.4 and 1.2.5.

cp
/lib/modules/2.6.16.27-0.6-smp/extra/ocfs2/cluster/ocfs2_nodemanager.ko
/lib/modules/2.6.16.27-0.6-smp/kernel/fs/ocfs2/cluster/
cp /lib/modules/2.6.16.27-0.6-smp/extra/ocfs2/dlm/ocfs2_dlm.ko
/lib/modules/2.6.16.27-0.6-smp/kernel/fs/ocfs2/dlm/ocfs2_dlm.ko
cp /lib/modules/2.6.16.27-0.6-smp/extra/ocfs2/dlm/ocfs2_dlmfs.ko
/lib/modules/2.6.16.27-0.6-smp/kernel/fs/ocfs2/dlm/ocfs2_dlmfs.ko
cp /lib/modules/2.6.16.27-0.6-smp/extra/ocfs2/ocfs2.ko
/lib/modules/2.6.16.27-0.6-smp/kernel/fs/ocfs2/ocfs2.ko

This is the location where suse puts modules for stock kernel so I just
deleted the old (in this case was 1.2.4 from a previous install) . I
could as easily left them in "extra" and did to test  but the modules do
not load in either location. How are you able to load the modules, even
the work around doesn't work?

Basically, if I remove all the ocfs2 modules and replace them with the
new compiled 1.2.5 in either location in mod. dir., I still get same
errors on loading from init.d script o2cb or manually. I do not see how
you are loading them at all or I am not sure about this. "If I move the
original modules away, it
works as expected."
