   Hi @fejsov, does your bootstrap Go work? Maybe run some simple program like
   GOROOT=/home/nikola/go /home/nikola/go/bin/go run hello.go
   Could you tell some detail about how you built the bootstrap Go? Noticed /opt/go in the stack trace.

   Hi @cherrymui , I can run hello.go without problems. Sure, I used this command:
   GOARCH=mips64le GOOS=linux GOROOT_FINAL=/home/nikola/go ./bootstrap.bash
   As for /opt/go, my src is located there.

   Hi @cherrymui, one thing I noticed this morning... Code generated for mips64le is actually MIPS-III version 1, not Mips64 rel 2. Maybe this caused error?

   MIPS-III should not be a problem. This is for compatibility with more hardware. Indeed the bootstrap Go is also a MIPS-III binary. What machine/OS are you running on?

   I tried to bootstrap with the same commit you used and it succeeded. So I don't know where I should look. Could you try a different version, say Go 1.6 and 1.7 release? If there is any difference, we can go from there.

   I use Cavium Octeon II V0.9 EP6300C (CN6335p2.1-1250-AAP). It's running Linux. I tried to use Go1.6 and 1.7 release. It seemed to be working, but crashed again (this time, after a lot of things done successfully). Here's the output:

   If you run with the same commit multiple times, do you get same failure? If not, one possibility could be the atomic operation is not really atomic on your machine. Could you run sync/atomic test with the bootstrap Go?

    After first try, I got OK for atomic. After that, I tried to compile Go on the board. I got different error than previously described. Again, I tried to run atomic test, but got Segmentation fault message.

    Is it the bootstrap Go? Could you paste the stack trace? That could be helpful.

    Hm... Now I got floating point exception. Here are the strace logs.
    atomic_bad.txt
    atomic_good.txt
    make.bash.txt
    First, I run atomic (atomic_good).
    Then, make.bash, and finally atomic again (atomic_bad).

    Hi @cherrymui. I think I found the problem. We have updated kernel (from 4.1 to 4.8) and it works as expected now.

    Do you know the exact kernel problem that the kernel update fixes? FTR, my mips64le builder machine (loongson 2F notebook) is running stock linux kernel 3.12.22, and it can bootstrap and test Go fine. I'd like to know the problem of older kernel for mips64le machines so that we can update golang.org/wiki/MinimumRequirements. Thanks.

    @minux, I don't know exact kernel problem. Building bootstrap on my board was giving different unexpected results (segfaults, floating point errors).
