Often enough nodejs -e 'console.log("hi");' is enough to crash it
from ci20_linux.

warning: GDB can't find the start of the function at 0x55b1c830.
GDB is unable to find the start of the function at 0x55b1c830
and thus can't determine the size of that function's stack frame.
This means that GDB may be unable to access that stack frame, or
the frames below it.
This problem is most likely caused by an invalid program counter or
stack pointer.
However, if you think GDB should simply search farther back
from 0x55b1c830 for code which looks like the beginning of a
function, you can increase the range of the search using the `set
heuristic-fence-post' command.

Does not repeat on @ZubairLK 's v3.18 but no SMP so that's not at all surprising.

You could take a look at the dev-mips-kitkat-v3.0.8 branch which has a number of cacheflush fixes for SMP. As far as I remember these fixes only affected a Java JIT and not V8, but it might be worth trying them as it looks as if there may be SMP cache flushing problems...

Good news! Repeats on 3.0.8 even with upper memory section dropped and with nosmp on kernel command line, this tells me it might actually be fixed... testing 3.18 next

More good news (for me), with kernel v3.0.8 and SMP but no high memory section in boot args, the problem does not repeat.

I cannot test with the high memory section because am unable to get my new kernel to boot with it, I get the following:
[ 15.390000] VFS: Mounted root (ubifs filesystem) on device 0:14.
[ 15.390000] Freeing unused kernel memory: 244K (80813000 - 80850000)

[ 15.480000]

[ 15.490000] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004
[ 15.490000]
My .config is here: http://sprunge.us/VYAB if anyone has a suggestion how I should change it to be able to boot with the high memory section.
