This may be related to my problem, though the symptom is different.
Since the same time (around the end of november) i tried many times to
build a SMP-enabled 4.9-STABLE kernel for my bi-athlon machine. It always
hangs (no error msg, total iresponsiveness) at the end of the kernel boot
(just before mounting filesystems).
I then reverted my cvs tree to use -RELEASE, and all is fine.
I did not yet try a non-SMP kernel. I'll do that asap.
