Hi Christian,

Sorry to resurrect this old thread, but I wanted to reply in case you
were still thinking about this for whatever reason. I was running into a
similar issue with building UML, and then I found Geert's reply [1] in a
related thread.

I'm not sure how you set your config initially, but what jumps out at me
is that CONFIG_STACK_WARN=1024 even though
CONFIG_64BIT=y. CONFIG_STACK_WARN defaults to 2048 for 64-bit builds,
which is why other people don't seem to be running into this issue (at
least from glancing over the mailing list).

Obviously, this doesn't solve the actual problem, but from Liam's reply
further up in the thread, it looks like he's working on a fix, so now
you can keep your eye out for that!
