This struck twice in a row this morning, causing the SheriffBot to go off with a false positive:

This is the same issue as in https://bugs.webkit.org/show_bug.cgi?id=36908.

Again, I will upload a patch shortly after.  The patch will not fix this bug but to gather more information.  Once we collect enough info I will upload a fix.

This patch is to gather more information of framebuffer status when failure happens.  It won't fix this failure issue.

Another patch will be uploaded once we gather the information we needed to confirm our educated guess on the cause of the random failure.
