Thank you John, emulation on s390x is imperfect at times - the JVM might just use a non emulated instruction or something like that. I've linked your upstream report (thanks) here to that the bug automatically gets updates from there. Do we already happen to know at which (maybe always the same) instruction sequence this crashes? ** Also affects: qemu-gitlab via https://gitlab.com/qemu-project/qemu/-/issues/655 Importance: Unknown Status: Unknown ** Changed in: qemu (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945540 Title: Java crashes on s390x VM with SIGILL/ILL_PRVOPC at '__kernel_getcpu+0x8' To manage notifications about this bug go to: https://bugs.launchpad.net/qemu-gitlab/+bug/1945540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The error still occurs on the same s390x virtual machine with QEMU version 6.1. After building QEMU 6.1, I started the virtual machine as follows: $ ../qemu-6.1.0/build/s390x-softmmu/qemu-system-s390x \ -m 2048 -drive if=virtio,file=s390x-focal.qcow2,cache=none The QEMU 6.1.0 monitor shows: (qemu) info version 6.1.0 On the guest, I installed the new 'openjdk-17-jre-headless' OpenJDK 17 package in Ubuntu 20.04. Although the installation fails because of this bug, the 'java' command is available after the attempt to install the package. $ sudo apt-get install openjdk-17-jre-headless The error in this bug report still occurs: $ /usr/lib/jvm/java-17-openjdk-s390x/bin/java --version # # A fatal error has been detected by the Java Runtime Environment: # # SIGILL (0x4) at pc=0x03ff9e4fe6f4, pid=2883, tid=2884 # # JRE version: (17.0+35) (build ) # Java VM: OpenJDK 64-Bit Server VM (17+35-Ubuntu-120.04, mixed # mode, sharing, tiered, compressed oops, compressed class ptrs, # serial gc, linux-s390x) # Problematic frame: # C [linux-vdso64.so.1+0x6f8] __kernel_getcpu+0x8 # # Core dump will be written.

There were some fixes in QEMU v6.1. Please try that one to see whether it solves your problem, too. ** Project changed: qemu => qemu (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945540 Title: Java crashes on s390x VM with SIGILL/ILL_PRVOPC at '__kernel_getcpu+0x8' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1945540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
