+Title:
+ qemu-img hangs on rcu_call_ready_event logic in Aarch64 when
+ converting images
+
+Status in QEMU:
+ In Progress
+Status in qemu package in Ubuntu:
+ In Progress
+
+Bug description:
+ On the HiSilicon D06 system - a 96 core NUMA arm64 box - qemu-img
+ frequently hangs (~50% of the time) with this command:
+
+ qemu-img convert -f qcow2 -O qcow2 /tmp/cloudimg /tmp/cloudimg2
+
+ Where "cloudimg" is a standard qcow2 Ubuntu cloud image. This
+ qcow2->qcow2 conversion happens to be something uvtool does every time
+ it fetches images.
+
+ Once hung, attaching gdb gives the following backtrace:
+
+ (gdb) bt
+ #0 0x0000ffffae4f8154 in __GI_ppoll (fds=0xaaaae8a67dc0, nfds=187650274213760,
