Diff between Linux-2.6.27-omap1-dirty and Linux-2.6.27-omap1 ?

["Shivdas Gujare" <shivdas.tech@gmail.com>]

Hi All,

I am working on testing Linux-2.6.27 omap kernel on beagle board.

I cloned kernel from
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git

and checked out to tag v2.6.27-omap1, I loaded kernel on beagle board,
and was able to boot properly like....

OMAP3 beagleboard.org # bootm 0x80300000
## Booting kernel from Legacy Image at 80300000 ...
   Image Name:   Linux-2.6.27-omap1
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1614320 Bytes =  1.5 MB
   Load Address: 80008000
   Entry Point:  80008000
   Verifying Checksum ... OK
   Loading Kernel Image ... OK
OK

Now, I done some operations, like checkout to master, checkout to
v2.6.26-omap1 and v2.6.25-omap1, loaded corresponding uImages to
beagle board
and was able to boot board every time.

After this, I again checkout to v2.6.27-omap1, compiled and loaded
uImage to beagleboard
But this time I am not able to boot the board.
and Got the message like

OMAP3 beagleboard.org # bootm 0x80300000
## Booting kernel from Legacy Image at 80300000 ...
   Image Name:   Linux-2.6.27-omap1-dirty
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1669176 Bytes =  1.6 MB
   Load Address: 80008000
   Entry Point:  80008000
   Verifying Checksum ... OK
   Loading Kernel Image ... OK
OK

Starting kernel ...

Uncompressing Linux...........................................................................................................
done, booting the kernel.

and it, stucks at here..

Here, the only difference I observed is "Image Name:
Linux-2.6.27-omap1" and "Image Name:   Linux-2.6.27-omap1-dirty",
where uImage with second Image name is not booting.

I think, I have done something wrong here, while compilation and checkout.

I just want to know in what cases "-dirty" is appended to linux kernel
Image Names or anything I done wrong?

Thanks for your Helps.
