Loading the kernel from the latest raspberry pi os image leads to this kernel panic running `QEMU emulator version 6.0.0`. The same happens with `bcm2708-rpi-zero.dtb` and also with older kernels. ``` $ qemu-system-arm -M raspi0 -kernel kernel.img -dtb ./bcm2708-rpi-zero-w.dtb -append 'earlyprintk earlycon=pl011,0x20201000 console=ttyAMA0 loglevel=8' -nographic -m 512M [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 5.10.17+ (dom@buildbot) (arm-linux-gnueabihf-gcc-8 (Ubuntu/Linaro 8.4.0-3ubuntu1) 8.4.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #1414 Fri Apr 30 13:16:27 BST 2021 [ 0.000000] CPU: ARMv6-compatible processor [410fb767] revision 7 (ARMv7), cr=00c5387d [ 0.000000] CPU: VIPT aliasing data cache, unknown instruction cache [ 0.000000] OF: fdt: Machine model: Raspberry Pi Zero W [ 0.000000] earlycon: pl11 at MMIO 0x20201000 (options '') [ 0.000000] printk: bootconsole [pl11] enabled [ 0.000000] Memory policy: Data cache writeback [ 0.000000] Reserved memory: created CMA memory pool at 0x18000000, size 64 MiB [ 0.000000] OF: reserved mem: initialized node linux,cma, compatible id shared-dma-pool [ 0.000000] Zone ranges: [ 0.000000] Normal [mem 0x0000000000000000-0x000000001bffffff] [ 0.000000] Movable zone start for each node [ 0.000000] Early memory node ranges [ 0.000000] node 0: [mem 0x0000000000000000-0x000000001bffffff] [ 0.000000] Initmem setup node 0 [mem 0x0000000000000000-0x000000001bffffff] [ 0.000000] On node 0 totalpages: 114688 [ 0.000000] Normal zone: 1008 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 114688 pages, LIFO batch:31 [ 0.000000] pcpu-alloc: s0 r0 d32768 u32768 alloc=1*32768 [ 0.000000] pcpu-alloc: [0] 0 [ 0.000000] Built 1 zonelists, mobility grouping on.
