Android RAMDUMP crashes after 82MB - TEE?

When performing a RAM dump, the process always stops after ~82MB, followed by a kernel crash and device reboot.  I think this might be due to the TEE at 0x5100000 (85MB)?

Is it possible to skip over the TEE, or start the dump after this region?

Android Kernel 4.9, this is the dmesg:
