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 -- Rafael David Tinoco <rafaeldtin...@ubuntu.com> Tue, 26 May 2020 17:39:21 +0000 Is there a way you can test Eoan or Focal's version ?
