Run the emulation with:
board/qemu: ensure root is available before mounting it On my machine, it happens once in a while that the virtualised machine boots too fast for the rootfs to be available at the time the kernel tries to mount it. For example, board/qemu/arm-vexpress/readme.txt suggested changing "-smp 1" up to "-smp 4". But doing so here causes a kernel panic: VFS: Cannot open root device "mmcblk0" or unknown-block(0,0): error -6 Please append a correct "root=" boot option; here are the available partitions: 1f00 131072 mtdblock0 (driver?) 1f01 32768 mtdblock1 (driver?) Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) So, add the oh-so-useful 'rootwait' option to all kernel command lines for qemu defconfigs. Signed-off-by: Yann E.
