The user provided a crash when running Java on an s390x VM with SIGILL/ILL_PRVOPC at '__kernel_getcpu+0x8'. + +First, I'll look at the error message: it's a SIGILL signal, which means illegal instruction. This suggests that the CPU encountered an instruction it couldn't execute. The problematic frame points to __kernel_getcpu in vdsolinux64.so.1. + +I know that s390x is IBM's mainframe architecture. QEMU provides emulation for this architecture, possibly using KVM as a hypervisor. The issue seems related to how certain system calls or instructions are handled by the emulator. + +The error occurs when Java runs, but the core of the problem is in '__kernel_getcpu', which is part of the kernel's vdso (virtual dynamic shared object). This indicates that the issue might be with how QEMU handles certain syscalls or traps on s390x. + +Looking at the possible categories: hypervisor seems relevant because KVM/QEMU acts as a hypervisor for virtual machines. If '__kernel_getcpu' is misbehaving, it could be due to an issue in the hypervisor's handling of CPU-related instructions or system calls. + +Other categories like device, network, or graphics don't seem to fit here.
