r247095 Boot Failure

[Shawn Webb]

I'm on r247095. My box is failing to boot on a Dell Precision T7500. I'm
running ZFS as root with a mirrored root pool.

Here's a pic of the box failing:

There isn't much useful information in the pic. No crash dump is generated.
Where do I go from here?

I can boot into kernel.old and that works as a workaround for now.

Thanks,

Shawn
