Bug#852612: Acknowledgement (linux-image-4.9.0-1-amd64: kernel 4.9.2-2 panics on boot)

[Robert Lange]

This bug is almost certainly related to this patch, which I believe is  
not in the currently packaged kernel:

https://git.kernel.org/cgit/linux/kernel/git/efi/efi.git/commit/?h=next&id=b2a91a35445229
The machine referenced in that patch is the Lenovo ThinkPad w541,  
which is a minor hardware upgrade of my w540.
