Public bug reported:
Docker and golang packages are not able to run on e870 machine due to a
lot of CPU on these machines.
The current machine has 400 CPUs and shows the following error:
runtime stack:
runtime.throw(0x654c60, 0x17)
/usr/lib/go/src/runtime/panic.go:530 +0x8c

while processing:
golang-go
golang-doc
golang
E: Sub-process /usr/bin/dpkg returned an error code (1)
Looking at the code I see:
_MaxGomaxprocs = 1 << 8
if old < 0 || old > _MaxGomaxprocs || nprocs <= 0 || nprocs >
_MaxGomaxprocs {
throw("procresize: invalid arg")
}
If I decrease the amount of CPU to < 256, I don't see a problem.
