[oe] how to know why bitbake will pick a wrong .bb file after providing PREFERRED_PROVIDER value

[srinredplano SP]

Hi ,
I am using *DISTRO=arago*  and *MACHINE= omap3axon*(same as that of omap3evm
) to compile* linux-2.6.22 * kernel .

when I try to execute the following   command
tbake finds my .bb file and uses

*$> MACHINE=omap3axon  bitbake virtual/kernel*

*wrong bb file is getting picked up . How to know why a wrong .bb file is
picked up(it always picks linux-nokia900-2.6.28.10+gitr0+
e93534addfc33a2fefbca13cb86a8f787e4b650c-r92.bb file  ) and which  variable
i have to override so that only my .bb file gets executed .
Is there any thing else which I am missing . thanks  in advance
