Hi Bruce,
We had a locked up qemuppc lsb image and I was able to find backtraces
from the serial console log (/home/pokybuild/yocto-autobuilder/yocto-
worker/nightly-ppc-lsb/build/build/tmp/work/qemuppc-poky-linux/core-
image-lsb/1.0-r0/target_logs/dmesg_output.log in case anyone ever needs
to find that). The log is below, this one is for the 4.9 kernel.
Failure as seen on the AB:
https://autobuilder.yoctoproject.org/main/builders/nightly-ppc-lsb/buil
ds/1189/steps/Running%20Sanity%20Tests/logs/stdio
Not sure what it means, perhaps you can make more sense of it? :)
Cheers,
Richard
