Can confirm: whenever I plug my Transcend USB microSD reader into my builder (amd64, r331284), the kernel does attach da0 then immediately panics and falls down to `db>` prompt.

I did not even have to plug-unplug the reader three times; plug the reader in and bam! immediate panic.

AFAIK, r331115 did not have this issue because I was able to update my RPi 2 with the very reader from the very builder.
I managed to salvage kernel binary dump; in case the dump is needed, please let me know.
