This has also been noted for the debian-ports built generic kernel,
for kernel versions 4.3 and above.  They fail to boot with symptoms
exactly as shown above.

There is some speculation on the debian-alpha mail list that only
a kernel built for generic system is failing to boot.  I have not
been able to confirm that.

I managed to build a 4.3 dp264 variant kernel which boots okay on an
XP1000, but my attempts to build a 4.3 or 4.4 titan variant kernel
is failing with relocation errors such as:

arch/alpha/kernel/built-in.o: In function `osf_filldir':
arch/alpha/kernel/osf_sys.o:(.text+0x278c): relocation truncated to fit: BRSGP against symbol `__copy_user' defined in .text section in arch/alpha/lib/lib.a(ev6-copy_user.o)

so I have not got very far with exploring the problem.

Cheers
Michael.
