Uggh... I missed since i was looking at non LPAE omap2plus_defconfig. Dual A15 OMAP5432 with multi_v7_defconfig + CONFIG_ARM_LPAE=y https://github.com/nmenon/kernel-test-logs/blob/next-20150123/multi_lpae_defconfig/omap5-evm.txt Dual A15 DRA7/AM572x with same configuration as above. https://raw.githubusercontent.com/nmenon/kernel-test-logs/next-20150123/multi_lpae_defconfig/dra7xx-evm.txt https://github.com/nmenon/kernel-test-logs/blob/next-20150123/multi_lpae_defconfig/am57xx-evm.txt Single A15 DRA72 with same configuration as above: https://raw.githubusercontent.com/nmenon/kernel-test-logs/next-20150123/multi_lpae_defconfig/dra72x-evm.txt You are right. the issue re-appears with LPAE on :( Apologies on missing that. > > > > -- > > Regards, > > Nishanth Menon > > > > _______________________________________________ > > linux-arm-kernel mailing list > > linux-arm-kernel@xxxxxxxxxxxxxxxxxxx > > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel > > [1] http://storage.kernelci.org/next/next-20150123/arm-multi_v7_defconfig+CONFIG_ARM_LPAE=y/lab-tbaker/boot-exynos5250-arndale.html > > [2] http://storage.kernelci.org/next/next-20150123/arm-multi_v7_defconfig/lab-tbaker/boot-exynos5250-arndale.html > > Cheers, > > Tyler -- Regards, Nishanth Menon -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
