And another one from restarted qemux86 build:

ERROR: Function failed: do_kernel_configme (log file is located at /home/jenkins/oe/world/shr-core/tmp-glibc/work/qemux86-oe-linux/linux-yocto/3.19+gitAUTOINC+f7a81274b4_43b9eced9b-r0/temp/log.do_kernel_configme.22612)

Log data follows:

NOTE: recipe linux-yocto-3.19+gitAUTOINC+f7a81274b4_43b9eced9b-r0: task do_kernel_configme: Failed

I understand that these error logs aren't very helpful, but the tmpfs is already gone.

All I can say was that I wasn't seeing these issues until yesterday.
