I didn't know where to find a vanilla FSF 4.6 toolchain for arm, so i rolled my own 4.6 toolchain using the Debian 4.6 source packages inside a sid chroot and i can confirm the problem is there too. Meanwhile while googling around i found i was not the only one experiencing this issue: https://lists.yoctoproject.org/pipermail/poky/2011-April/005703.html and https://lists.yoctoproject.org/pipermail/poky/2011-May/005763.html then the thread continued in June with some disassembly/low level debugging and a couple of workarounds (neither of them worked for me anyway): https://lists.yoctoproject.org/pipermail/poky/2011-June/006634.html Last but not least, i can confim this issue is present in linaro, ubuntu and vanilla kernels going back to at least .35.x (actually the only .35 i tested was ubuntu maverick), and it affects omap4 too. I couldn't test 3.0 since it kernel panics at boot (but that should be another issue). -- bye, p. _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
