This issue would block MTBF testing on Nexus 5 L, nominate to 2.2.
Hi Viral, any idea for this problem?

the error log looks like cpu met some error and can't bring up.
It's a kernel issue should be less relative to b2g.

We get kernel source code from CAF and did not modify any cpu part in our side.
If changing kernel in MTBF is acceptable, we can provide local build to see if we can avoid this kind of issue.

Thanks for the ni.  We have not seen this issue in our builds, our gonk and below is different from hammerhead.

Until now, we have executed MTBF with Nexus-5-L-5.1 9 times, did not hit this shutsown issue.
