There are two logs when building go1.9.2 
First, NetBSD 8.0_BETA/netbsd-8's kernel at 2017.10.24 before pullup
ticket #326,

https://gist.github.com/oshimaya/00c3d5e17b7b17ce5e78bc2b46680bc9#file-armv6_go1-9-2_build_fail-log

This shows the error,
go/src/math/pow10.go:22:78: internal compiler error: ovf in Mpflt Float64

However, this problem will somtimes occur, sometimes not occur.

Second, after pullup #326:

https://gist.github.com/oshimaya/00c3d5e17b7b17ce5e78bc2b46680bc9#file-armv6_go1-9-2_build_panic_20171024-log

During compiling math/big,
Kernel panic by assertion in src/sys/arch/arm/vfp/vfp_init.c#523

This promblem sometimes occurs and somtimes not occurs, too.

I met this problem only with earmv6(RPI), never with earmv7(RPI2).

And more, in newer kernel(ex. 20180108 for netbsd-8),
another problem appears,
During to build go1.9.2, sometimes a kernel hangup occurs.
I have not examined anything about this yet.

Thanks.
