I am using next.git/master with this patch applied: https://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git/commit/?h=features&id=8aa8680aa383bf6e2ac I am using QEMU with the mvcos patch and your patch applied (and a patch that allows enabling csst/csst2). I am using the following qemu command line: #!/bin/bash /home/dhildenb/git/qemu/s390x-softmmu/qemu-system-s390x \ -nographic -nodefaults -machine s390-ccw-virtio,accel=tcg \ -cpu qemu,mvcos=on,stfle=on,ldisp=on,ldisphp=on,\ eimm=on,stckf=on,csst=on,csst2=on,ginste=on,exrl=on\ -m 256M -smp 1 -chardev stdio,id=con0 \ -device sclpconsole,chardev=con0 \ -kernel vmlinux -initrd /home/dhildenb/initrd.debian Right now, I can start a z9 compiled kernel. When trying to start a z10 compiled kernel (which generates many csst), qemu simply crashes / the guests exits (have to debug) without any command line output. So either something in csst is broken or in the other instructions for z10. -- Thanks, David
