Is there a known issue with running multiple instances of

Key presses didn't work, SDL window doesn't close, at 99.9% CPU.
Huh? This is all generic code O_o. And no, it's not a known issue.
Hm, reproducable by running
$ s390x-softmmu/qemu-system-s390x
(without arguments) on s390-next branch.
I get compat_monitor0 console, but monitor or switching to real console
don't work and neither does closing. Same backtrace.
Doesn't happen with ppc-softmmu/qemu-system-ppc or x86_64. Maybe an
issue with the monitor, only apparent when then monitor is shown at
startup rather than later user-invoked? Any suggestions?
Maybe the guest is executing an endless loop? Could you try to compile this asm
blob for ppc and execute it with -kernel?
Test.S:
_start:
b .
Compile with gcc test.S -nostdlib
Nope, doesn't hang.
Hrm. Paolo, any idea?
Alex
