We are using 2.6.34.10 (can be upgraded to 2.6.34.14). We are consider of ext3 or ext4. Even in wikipedia, it mentions ext4 is stable from 2.6.28, I still have some doubts: >>> >>> 1.

If you are looking at stability for a commercial application, I think you would be best off to choose something like RHEL6 2.6.32 which has back ported all of these patches for ext4 already and will continue to get fixes for years to come. Next best would be to pick something like FC18 3.8(?), which also has the needed patches, but will not be supported for as long a time. This is definitely still better than picking the vanilla kernel of the same version. That way, you can focus on your application, and not on becoming a kernel maintainer...
