Description Yi Zhao 2012-04-09 07:36:45 UTC 
For some bsp in autobuilder, the version field in the kernel name is incorrect.

For example: http://autobuilder.pokylinux.org/nightly/20120405-1/machines/mpc8315e-rdb/

The kernel name is uImage-3.0.24+git1+a4ac64fe873f08ef718e2849b88914725dc99c1c_1+7ba6d6853b6e7cf00a742baeba1503c80fc05314-r4-mpc8315e-rdb-20120405071926.bin, but it is real version is 3.0.23.

Comment 1 Beth Flanagan 2012-04-09 20:17:13 UTC 
Not an autobuilder bug. The autobuilder does not determine the name of uImage. It seems that:

LINUX_VERSION ?= "3.0.24" 
PV = "${LINUX_VERSION}+git${SRCPV}"

is innaccurate in meta/recipes-kernel/linux/linux-yocto_3.0.bb 

Reassigning to kernel team.
Comment 2 Darren Hart 2012-04-09 20:24:23 UTC 
If we checkout the BSP branch and read the Makefile, we see:

VERSION = 3
PATCHLEVEL = 0
SUBLEVEL = 24

So the sources will build a 3.0.24 kernel, and as noted by Beth in Comment 1, the recipe also reflects a 3.0.24 kernel.

It appears that for whatever reason, the image on the autobuilder has not rebuilt the kernel image from the new sources.

Note that for the uImage listed (machine sources 7ba6d6853b6e7cf00a742baeba1503c80fc05314), 3.0.23 is correct. This is the machine SRCREV in meta-yocto. The correct fix is to update the machine SRCREV to what is current in the BSP branch.

Bruce, was this an omission, or has the mpc machine been held back deliberately?

(Sorry for my previous incorrect change to the Whiteboard -- I didn't use the correct link...)
Comment 4 Bruce Ashfield 2012-04-10 04:27:58 UTC 
looks like an omission for meta-yocto. will update ASAP.
