+qemu arm no longer able to boot RPI Kernels
+
+Since RPi Kernel 1.20170427, qemu is no longer able to emulate the Rasberry Pi, as the linux kernel is complaining about timing issues.
+
+Old kernel output - https://pastebin.com/wvkneNNF
+New kernel output - https://pastebin.com/QTwgCkV2
+
+Note that the actual error is caused by the kernel being unable to get the timing source for the mmc (Line 160), which causes an unable-to-mount-root panic.  There are other issues with the serial port returning an invalid speed, which displays a divide-by-zero error, which is PROBABLY a symptom of the same root cause.
+
+This is simple to replicate - The last working kernel is available here:
+
+https://github.com/raspberrypi/firmware/tree/1.20170405/boot
+
+Download kernel7 and the dtb, and try to boot with (for example)
+
+qemu-system-aarch64 -M raspi2 -kernel kernel7.img -dtb bcm2709-rpi-2-b.dtb -serial stdio -sd noobs.img -append "root=/dev/mmcblk0p2 init=/bin/bash"
+
+This works, and boots successfully.   
+
+However, if you replace the kernel7.img and dtb with ones taken from https://github.com/raspberrypi/firmware/tree/1.20170427/boot it will NOT boot because of various clock timing issues (as in the second paste)
