+Qemu User (x86_64) Hangs after futex function not implemented error
+Description of problem:
+Qemu User hangs on futex call with the following last strace
+```
+futex(0x0000004001a01654,FUTEX_PRIVATE_FLAG|FUTEX_UNLOCK_PI,0,NULL,NULL,0) = -1 errno=38 (Function not implemented)
+```
+This is the last call until giving a SIGINT with CTRL + C where the following strace is output
+```
+futex(0x00000040b0085180,FUTEX_PRIVATE_FLAG|FUTEX_WAIT,2,NULL,NULL,0) = -1 errno=4 (Interrupted system call)
+--- SIGINT {si_signo=SIGINT, si_code=SI_KERNEL, si_pid=0, si_uid=0} ---
+
+```
+Steps to reproduce:
+1. Install steamcmd https://developer.valvesoftware.com/wiki/SteamCMD
+2. In the steamcmd shell install Valheim dedicated server with `app_update 896660`
+3. Navigate to the downloaded app `cd ~/Steam/steamapps/common/Valheim\ dedicated\ server/`
+4. Run `qemu-x86_64 valheim_server.x86_64`
+5. The process hangs as per description.
+Additional information:
+The issue was originally encountered on a raspberry pi ARM64 host using the ubuntu 5.2.0 version of qemu. Installed cross libararies:
+* libc6-amd64-cross
+* libgcc-s1-amd64-cross
+
+It was then replicated on the x86 host fedora with a build of the qemu master branch.
+The full qemu -strace output is provided below
+[qemu_strace_output.log](/uploads/96e0e31b1e63191a94d73f05023c5173/qemu_strace_output.log)
+
+The expected output found when running `strace ./valheim_server.x86_64` without qemu on the x86_64 host is attached below
