I have noticed the problem with vanilla Linux 4.8.11 from kernel.org, so
I suspect the Debian kernel is affected as well. There is no console
output at all, the system freezes right when uncompressing the kernel.
It should be noted that I haven't noticed the problem on my desktop
(which has a 32-bit userland but a 64-bit kernel) where I have
CONFIG_KERNEL_GZIP=y, but on my laptop which uses the default
CONFIG_KERNEL_XZ=y it is reproducible.
Cheers,
Sven
