I have pushed updates to the branch here: https://github.com/ffainelli/linux/pull/new/kasan-v7 which defines CONFIG_KASAN_SHADOW_OFFSET from the PAGE_OFFSET value directly, and recalculate KASAN_SHADOW_START/END accordingly using the same formula as ARM64. can you try them out? If that still does not work, can you detail the imx6qdp memory layout a little more? Any chance of running a kernel with DEBUG_LL/EARLYPRINTK turned on so we can see where the problem could be? -- Florian
