While in the failing run, that  output-free time is 12-13 minutes long.
This seems to have started happening on mozilla-central in this merge: https://tbpl.mozilla.org/?jobname=b2g_emulator_vm%20mozilla-central%20opt%20test%20reftest-8&rev=76b55c0850ca 

The prior pushes (clicking the green arrow on tbpl) have done several dozen retriggers of R8 and they're all green.

Working on bisecting this further once the hg.m.o troubles get dealt with.
Flags: needinfo?(kwierso)
So, the failures start up on this push: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&jobname=b2g_emulator_vm%20mozilla-inbound%20opt%20test%20reftest-8&fromchange=813ad3e96004&tochange=76b55c0850ca&rev=d9382edf1265

As the prior push doesn't have the failure: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&jobname=b2g_emulator_vm%20mozilla-inbound%20opt%20test%20reftest-8&fromchange=813ad3e96004&tochange=76b55c0850ca&rev=4c995a0d9166

I'm guessing the tests Seth added in Bug 942364 and Bug 925611 changed which chunks tests run in, so tests at the end of one chunk now run at the start of another chunk, where they fail.

Yeah, seems like reordering of tests is about the only possible explanation here. (After all, those commits only add tests - they don't change any code at all.)

I'm probably not the right person to actually get this problem fixed, as I don't know much about WebGL. I'm gonna kick this over to Jeff, who I suspect is either the right person or knows who is.
