U-Boot can't be build with make -j16.
Second pass passes fine.
Didn't investigate myself and probably will not have time (near to
vacation time for me).
So, please, fix it before release.

So, first time it's being built, consequent runs usually failed.

More information:
- when consequential run is being executed no code had been changed
- the object files where it fails is totally arbitrary
- I used ccache, though I disabled for now completely (through
modifying PATH) and problem still exists
- Linux kernel rebuilds on that very same machine fine (like touch
include/linux/perf_event.h; make -j64 in a loop)
It's total mystery to me. It was rebuilding just fine yesterday, I
updated today from GH and even older (v2018.09-rc2) fails.

I assume this is on Debian/unstable? I can't directly replicate this on
my 24core (Debian/stretch) or 16core(Ubuntu/xenial) machines. I'll
setup a chroot soon, but since you've said -j64 is fine there too I
suspect you have more cores than I. This may be something you have to
bisect for us if I can't replicate it myself. Can you confirm how many
cores you have? I might be able to spin something up in Google compute.
Thanks!

$ sed -n -e '/cpu cores/ { p; q }' /proc/cpuinfo
cpu cores : 22
OTOH, I tried on my desktop (where is unstable) and everything works
fine with the same (-j16) command line on any gcc I tried.
$ sed -n -e '/cpu cores/ { p; q }' /proc/cpuinfo
cpu cores : 4

Did few runs (~6) on this machine with -j4, no failures so far.
Reruning same with -j16 brings failure on ~2-3 iteration.
It seems the scope can be narrowed to:
- many cores build system, and
- Debian testing/unstable toolchain, and/or
- U-Boot build system

I'm pretty sure it's a dependency problem somewhere. Since this was
working reliably for you recently (right?) and I can't reproduce it and
you can, if you can run a git bisect to figure out what commit is
breaking things, that would be very helpful. Thanks!

Now after my vacation.
So, I guess it's not so critical for release as I thought at the beginning.

I'd love to fix it, but I can't replicate it.

I can't reproduce this on my machine too, on Ubuntu 16.04 with either
native gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10), or
the kernel.org gcc (gcc version 7.3.0 (GCC)), using below commands:
$ make clean && make edison_defconfig && make -j64

There was a patch recently to make 4.2.1 to fix some parallel build issue.
No idea if that fix applies to your case though.

I've seen this problem - building inside a VMware VM. I've always
found that logging out and back in appears to fix it, so possibly
something related to the session... I've similarly failed to figure
out what the problem is as it comes and goes.

I am no expert, but I/O error to me indicates a hardware problem on
the build machine and not necessarily a software issue.

Not exactly. AFAIR it's a message mapped to EIO errno.
The scenario can be like that (hypothetically), make runs compiler,
but instead of compiler ccache is being called and, in case it's
somehow broken, it might try to access to wrong block on the block
device which returns EIO on some (read()?) system call.

I doubt that is the issue. While EIO can be returned in response to a
hardware failure, it would be very random and most likely affect
something - the linker, a compiler - that process a lot of files or
data, not an echo command.

This is likely on track to the real problem. What happened is
something echo did returned EIO as an errno. That failing syscall was
probably a write(3), since echo doesn't do a whole lot else! And why
can write(3) return EIO, besides a hardware error?
EIO The process is a member of a background process group
attempting to write to its controlling terminal, TOSTOP
is set, the calling thread is not blocking SIGTTOU, the
process is not ignoring SIGTTOU, and the process group of
the process is orphaned. This error may also be returned
under implementation-defined conditions.
I think there's a $(shell echo something &) or something like that
somewhere.

I observe similar issue when I build QEMU except that its makefiles
use 'printf' instead of 'echo' in the 'quiet-command' macro. But I observe
the same issue even when building with V=1, i.e. when 'printf' is not
used. In that case the error comes from the make itself.
I tested a range of make versions from 3.81 to 4.2.1 and see the issue
with all of them.
When it happens under strace it looks like this (make V=0):
8341 write(1, " CC arch/AArch64/AArch64Di"..., 45) = -1 EAGAIN
(Resource temporarily unavailable)
or this (make V=1):
31716 write(1, "c++ -I/usr/include/pixman-1 -W"..., 1024) = 1024
31716 write(1, "tcg-op-gvec.o tcg/tcg-common.o t"..., 10240) = 7936
31716 write(1, "ut-keymap.o ../ui/input-legacy.o"..., 2304) = -1
EAGAIN (Resource temporarily unavailable)
31716 write(1, "\n", 1) = 1
I suspect that it's a kernel issue, as I started to notice it after the
system upgrade from Debian 8 to Debian 9.
