I have been unable to get mochitests running on panda board (android 4.0.4) and fennec 17 for the last couple weeks. I have been able to run from the same build and toolchain on my tegra with no problem. When comparing the logs, a few things are out of order, but these things are missing at the end of the logcat output on the panda: 01-04 05:55:35.566 I/GeckoApp( 1561): Got message: Tab:ViewportMetadata 01-04 05:55:35.576 I/GeckoApp( 1561): Got message: Content:StateChange 01-04 05:55:35.576 I/GeckoApp( 1561): State - 786448 01-04 05:55:35.576 I/GeckoApp( 1561): Got a document stop 01-04 05:55:35.576 I/GeckoToolbar( 1561): zerdatime 179274 - Throbber stop by missing, I mean nothing at all shows up in the logcat output. I have more debugging to do, but this is a non starter for using panda boards to run automated tests. For comparison we can run reftests completely on the boards with the same build and tool chain.

I have a phone with Android 4.1.1 (Nexus S), and I can run mochitests just fine on there with the same build of fennec and the same tools/tests that fail on my panda board. I suspect the problem is our OS build, maybe a resource that we depend on (either directly or indirectly) which isn't available and we are hanging.

adjusting the resolution from the bootargs resolved this.
