[FYI] GCC segfaults under heavy multithreaded compilation with AMD Ryzen

[FYI] GCC segfaults under heavy multithreaded compilation with AMD Ryzen

# I'm a LKML subscriber, but not a x86 list subscriber

I found the following new linux kernel bugzilla about Ryzen related problem.
Since many developers don't check this bugzilla and I've also
encountered this problem,
I decided to introduce this problem here.

What I want here is that this problem is known by many people,
especially by x86 experts,
asking the hint to find the root cause, and making the reliable
workaround patch.

Summary of this problem from my point of view:
- gcc sometimes fails with SEGV at random
- at least part of this problem is caused by running instructions at
"RIP - 0x40"
- tens of people encountered this problem
- probably it is a hardware problem: many OSes WSL, NetBSD, and
FreeBSD encountered the very similar problem. In addition, this
problem happens with ECC memory and  memtest86 clean memory
- the root cause is not found yet. AMD have seemed to try to find it
for several months, but there have been no update from AMD yet
- There are workaround patch in FreeBSD, but it's not sure that it's a
reliable one since the root cause is not sure

Fore more detail, please refer to the links at the above mentioned bugzilla.

Historically we've seen exactly these symptoms on all kinds of systems
where the memory is at fault, even in cases where memtest86 passes.
Whether there's a specific problem on some Ryzen boards is a question for
AMD, but if I saw this without knowing the CPU I'd suspect memory
firstly. GCC it turns out is by accident an amazingly effective memory
testing tool.

If it is memory corruption problems then no - the kernel cannot work
around that level of hardware failure. The BIOS may be able to if it is a
board or compatibility problem as memory tuning is usually done by the
BIOS.

People are seeing these segfaults even with ECC memory (and EDAC
enabled). There are no ECC related MCEs in their logs.

Also for some the segfaults are gone after they RMAed their CPU.
Others are not so lucky and they still see segfaults after RMA.

For me it looks like a chip binning issue

Apparently, you can RMA your CPU:

Sorry for late reply and thank you for letting me know. I've already RMA'ed my
CPU and the new one works fine. I have one more Ryzen which I got for
investigating
this problem and I'll RMA it soon.

I'm affected, too.

I'm using Asus PRIME X370-PRO / 32 GB RAM (Kingston Hyperx
HX424C15FBK2/32) configured as suggested by bios 0805 (Agesa 1.0.0.6):
2400 MHz.
Problems happen with linux 4.12.x or 4.9.x (didn't test others).

It seems that things may run more stable if the machine is booted twice:
At first boot until password request for hd encryption, then hard reset again.


During kernel compiling, I can see those crashes and hard lockups, ...:

It also happened, that compiling just hangs, because two processes wait for each other.

That's surely true. But meanwhile, I got rid of my memory problems (no
more traces like these [1] or even system hangs) by a correct memory
configuration, but the segfaults of gcc remain, most of the time with
kernel 4.12, kernel 4.11.x and 4.9.39ff are working mostly fine -
mostly, because I stopped tests and can't therefore say, if it's really
stable or not - but (k)aslr must be disabled always.

FreeBSD meanwhile provides this workaround after long research [2]:

Please port it to Linux!
