Great, then the kernel is working just fine! :)
Seriously, without some sort of hint, it's going to be impossible for us
to know what to do here...

Ander is bisecting this problem.
OTOH, I am looking into test history and found the head commit is booting pass.
The problem report I have sent is a head-1 test report.
This means that, current Linus master boot pass.
Do you see any relation of top fix commit vs the report I sent.
BAD: 965181d7ef7e (head -1 )
GOOD: d888c83fcec75194a8 ( head)

fs: fix fd table size alignment properly
Jason Donenfeld reports that my commit 1c24a186398f ("fs: fd tables have
to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
embarrassing brown-paper-bag bug.
Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
reason they might not be aligned is because the incoming 'max_fd'
argument might not be aligned.
But aligining the argument - while simple - will cause a "infinitely
big" maxfd (eg NR_OPEN_MAX) to just overflow to zero. Which most
definitely isn't what we want either.
The obvious fix was always just to do the alignment last, but I had
moved it earlier just to make the patch smaller and the code look
simpler. Duh. It certainly made _me_ look simple.
Fixes: 1c24a186398f ("fs: fd tables have to be multiples of BITS_PER_LONG")
