I rebuilded the code and checked the 0x12004d7f8

12004d7f4:   1020038e        beqz    at,12004e630 <runtime.findrunnable+0xef0>
12004d7f8:   00000000        nop

12004d800:   ffa90090        sd      a5,144(sp)

Maybe it's async preempted with wrong quatum value some where in the compiler since it jumps to NOP.
It's more weird that runtime.findrunable shouldn't be preempted.

if hasPrefix(name, "runtime.") ||
        hasPrefix(name, "runtime/internal/") ||
        hasPrefix(name, "reflect.") {
        // For now we never async preempt the runtime or
        // anything closely tied to the runtime. Known issues
        // include: various points in the scheduler ("don't
        // preempt between here and here"), much of the defer
        // implementation (untyped info on stack), bulk write
        // barriers (write barrier check),
        // reflect.{makeFuncStub,methodValueCall}.
        //
        // TODO(austin): We should improve this, or opt things
        // in incrementally.
        return false, 0

instruction bytes: 0x0 0x0 0x0 0x0 0x2f 0x48 0x22 0x0 0x90 0x0 0xa9 0xff 0x48 0x20 0x17 0x3c

0x0 0x0 0x0 0x0 is just a NOP instruction.

There is nothing wrong to jump to a NOP. The question is why it SIGILLs at a NOP instruction.

I make Go net.test by 10000 times it all passed.
You are right, I've tried direct jump into NOP by

.text
__start:
        li  $a0, 0
        li  $v0, 4004
        dla $a1, msg
        li $a2, 13
        syscall
        li      $a0, 1
        dla     $a0, l1
        #daddi  $a0, 4 // adding this line
        j       $a0
        li      $v0, 4001
l1:
        li      $a0, 0
        nop
        li      $v0, 4001
        syscall
        raw $0x0, $0x0
        db $0x0, $0x0
.data
msg: .asciiz "Hello World\n"

And it's totally fined.
