http://tinderbox.mozilla.org/showbuilds.cgi?tree=TraceMonkey 'Linux tracemonkey unit test' turned orange with Mochitests timing out yesterday. Backing out the guilty patch did not fix it and it's been orange ever sense. Could someone please go see if something funny is going on with that machine, maybe reboot it and see if it magically goes green? Or just drop by #jsapi to discuss?
I chatted with jorendorff and others on IRC about this. I don't think kicking any machines will help here, there was 3 mochitest timeouts today, all on different slaves. bsmedberg kicked a build of 8d1c9cd07f91 that went green. A subsequent build of 569acf636d50 went orange again. Given that, I'm pretty sure this is in the code, and not a machine issue.
