Bit more details: 1. the assert started appearing from https://git.qemu.org/?p=qemu.git;a=commit;h=09e0c771e47 - this one just added the assert; 2. if removed, then another assert alerts: qemu-system-ppc64: /home/aik/p/qemu/block/io.c:1423: bdrv_aligned_pwritev: Assertion `child->perm & BLK_PERM_WRITE' failed. child->perm == 1 when this happens.
