Thanks for the feedback.
It looks like this happens because of:
/*
* There cannot be two concurrent aio_poll calls for the same AioContext (or
* an aio_poll concurrent with a GSource prepare/check/dispatch callback).
* We rely on this below to avoid slow locked accesses to ctx->notify_me.
*/
assert(in_aio_context_home_thread(ctx));
added by the last update:
qemu (1:2.11+dfsg-1ubuntu7.27) bionic; urgency=medium
* d/p/ubuntu/lp-1805256*: Fixes for QEMU on aarch64 ARM hosts
- aio: rename aio_context_in_iothread() to in_aio_context_home_thread()
- aio: Do aio_notify_accept only during blocking aio_poll
- aio-posix: Assert that aio_poll() is always called in home thread
- async: use explicit memory barriers (LP: #1805256)
- aio-wait: delegate polling of main AioContext if BQL not held
- aio-posix: Don't count ctx->notifier as progress when polling

Is there a way you can test Eoan or Focal's version ?
Thank you for reporting this bug.
