Comment 1 Darren Hart 2012-12-13 15:59:06 UTC 
Tom, this looks odd with cedartrail and fri2 appearing in the log, so it may be an sstate bug. Can you have a look and confirm that this builds?

Cristian, can you confirm that the log reported below is correct? It includes both cedartrail and fri2-noemgd...
Comment 2 Stoicescu Cornel 2012-12-13 16:58:12 UTC 
Also please refrain from using autobuilder links as they expire and information is lost.
Comment 3 Cristian Iorga 2012-12-13 17:13:20 UTC 
The same error appears on cedartrail and also on fri2.
Comment 4 Tom Zanussi 2012-12-13 22:37:55 UTC 
I'm not able to reproduce it here with the same commits:

Comment 5 Tom Zanussi 2012-12-14 02:45:39 UTC 
Also, not seen with fri2-noemgd + DISTRO = poky-lsb and 'bitbake core-image-lsb core-image-lsb-sdk -k' - this built fine.
Comment 6 Tom Zanussi 2012-12-14 02:57:26 UTC 
So, looking at the actual build directories on the autobuilder, we see the following error saying it can't find the git directory in the workdir:

tomz@yocto-iab09:/srv/home/pokybuild/yocto-autobuilder/yocto-slave/cedartrail/build/build/tmp/work/cedartrail-poky-linux/lttng-modules/2.0.5-r0/temp> less log.do_make_scripts

/srv/home/pokybuild/yocto-autobuilder/yocto-slave/cedartrail/build/build/tmp/work/cedartrail-poky-linux/lttng-modules/2.0.5-r0/temp/run.do_make_scripts.27949: line 113: cd: /srv/home/pokybuild/yocto-autobuilder/yocto-slave/cedartrail/build/build/tmp/work/cedartrail-poky-linux/lttng-modules/2.0.5-r0/git: No such file or directory


But listing it shows it's in fact there:

tomz@yocto-iab09:/srv/home/pokybuild/yocto-autobuilder/yocto-slave/cedartrail/build/build/tmp/work/cedartrail-poky-linux/lttng-modules/2.0.5-r0/temp> ls -al /srv/home/pokybuild/yocto-autobuilder/yocto-slave/cedartrail/build/build/tmp/work/cedartrail-poky-linux/lttng-modules/2.0.5-r0/git

So it is actually there, but apparently it wasn't when that task (run_do_make_scripts) was run, which means we probably have a race.
Comment 7 Tom Zanussi 2012-12-14 05:28:41 UTC 
I sent a patch that might fix this - basically trying to make sure do_make_scripts can't happen before do_unpack as seems to be happening in this case.
