Hi, Since updating to 3.13-rc1 I experience freezes on my Tegra based module after 2-5 minutes after boot up. There is no stacktrace, the serial console is dead as well as X turns black. I did a git bisect and could isolate the offending commit: f52bb722547f43caeaecbcc62db9f3c3b80ead9b ARM: mm: Correct virt_to_phys patching for 64 bit physical addresses My main cross compile toolchain is Linaro gnueabihf 4.7 (2013.04). I also tested with Linaro gnueabihf 4.8 (2013.11). I use tegra_defconfig with CONFIG_ARM_PATCH_PHYS_VIRT enabled. The module uses the Tegra T20 SoC featuring two A9 ARM cores and no NEON extension. I use a Yocto based root filesystem. Let me now if I can help with testing... -- Stefan -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
