I know there is a probably still problem with memory ordering of the host, but I have also seen some very old commits which could potentially help with it. But anyway, with version qemu-i386 version 3.1.0 (Debian 1:3.1+dfsg-7) I can see OpenRC starting up services and then the kernel crash. With version QEMU emulator version 3.1.93 (v4.0.0-rc3-dirty) The whole machine crash with this error: Illegal instruction Using command: ./qemu-system-i386 -cdrom alpine.iso --accel tcg,thread=multi Full Console Output: qemu-system-i386: warning: Guest expects a stronger memory ordering than the host provides This may cause strange/hard to debug errors Illegal instruction Kernel: Linux raspberrypi 4.14.98-v7+ #1200 SMP Tue Feb 12 20:27:48 GMT 2019 armv7l GNU/Linux CPU: ARMv7 Processor rev 5 (v7l) Features: half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm 4 cores To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1824768/+subscriptions
