Hi,

* continued to look into latrace and found an issue in case a dynamic library gets unloaded. Otherwise latrace looks quite good on ARM. https://wiki.linaro.org/KenWerner/Sandbox/latrace

* chasing bugs: - After a lot of testing Andy Green has made a big step forward in finding the root cause for the shut-down issue of my PandaBoard. The PMIC is seeing an overcurrent and issues an interrupt that gets ignored by current kernels. Then the PMIC shuts the board down for safety reasons. As a workaround Andy has made a kernel patch for the twl6030 driver that enables all interrupt sources. The kernel will acknowledge the overcurrent reported by the PMIC and the board survives. A patched kernel binary can be found at: https://wiki.linaro.org/KenWerner/Sandbox/708883

- While testing Andys patches on the linaro natty kernels I ran into https://bugs.launchpad.net/bugs/720055

- The flash-kernel utility doesn't work on the PandaBoard because the subarch check expects omap4 instead of omap: https://bugs.launchpad.net/bugs/721147

- Looked into the apr fail (process shared mutex's fail on armel v7). Their mutex functionality can be mappped to various methods, but only pthread is of interest here. The code relies on pthread_mutex_lock and pthread_mutex_trylock which is implemented by the (e)glibc. The c library uses GCCs __sync primitives if eglibc >= 2.12.1-0ubuntu11 and GCC >=4.5. The testprocmutex testcase passes now. https://bugs.launchpad.net/bugs/604753
